We are delighted to announce the release of our next major update, which will be available later today is live as of now. We’ve added some new features by popular demand, as well as tuned up our performance. We’ve got the juicy details further below.  By default your Live Mesh client will automatically update itself within 24 hours of the new build being posted, but you can always right click the Notifier icon in the system tray and choose to force an immediate update.  We'll update this blog post once the update is available.

The team has also been hard at work on our developer platform. We are on track to share that work with the world at PDC ’08 (Oct 27-30 in Los Angeles.) You can see a few of our sessions on the agenda page, including “Live Platform: New Developer Services and APIs”, “Live Platform: Building Mesh Applications” and “Live Platform: Mesh Services Architecture Deep Dive”. We’ve seen a lot of interest in our platform experience – the “app” that is the face of Live Mesh today. But Live Mesh is fundamentally a developer platform, and our goal is to enable a wide range of applications that build on our relationship directory and communications and synchronization infrastructure. If you haven’t seen Ori’s Channel 9 video on the platform, take a look to see what we’re getting at.

New Features

· Sync Live Mesh folders peer-to-peer only, excluding your Live Desktop. This will make it possible to synch files across your devices (or with devices of other members of a Live Folder) without consuming any storage space or quota in the Live Mesh cloud storage service. For completeness sake, though, we should mention that it’s not a 100% P2P synch – to optimize the synch experience we still use the cloud to store the authoritative metadata for the folder (for example, the file list and change history) and to broker encrypted P2P connections between clients. But the files themselves will not be stored in the cloud. Also, note that only the creator of a Live Mesh folder will have permission to change the cloud synch settings, since all the contents of a Live Mesh folder (no matter which user uploaded them) get charged against the quota of the folder’s creator.  We've got some details on how peer communications and synch work up today on Channel 9.

· File conflicts management on the Live Desktop. Pretty much speaks for itself. The same ability to view and resolve conflicting edits to a file that you’ve had in the Windows client is now available on the Live Desktop. Actually, we think it’s an even better experience, since we took the opportunity to streamline the UX when we implemented it for Live Desktop (we’ll bring the same improvements to the client in the future.)

· Added news events for New Live Mesh folder and Delete Live Mesh folder. We’re continuing to tune the news feed to provide the right set of information you need to keep track of what’s happening across your mesh.


· Improved performance when syncing files peer-to-peer. David and Trevor get into some of the details of where we found room for improvement in today's video.

· Better coalescing for news events. In non-geek speak, that means we’ll do a better job showing you only one news event when a user makes a bunch of changes in quick succession.

· News performance and scale improvements. Faster and better, new and improved, it slices and dices!

Windows Vista User Account Control (UAC) Update

In our last client release, we removed the requirement for UAC to be enabled when running on Vista SP1.  If you originally installed the Live Mesh software with UAC enabled, then got this update and disabled UAC, you might have some issues upgrading.  We'll have an announcement on the forum shortly with details of how to fix.

Last, a technicality for those keeping score at home -- the version number referenced in the title, 0.9.3103.2, is what you'll see in the client software.  The version number in Live Desktop will  be 0.9.3103.3, since we did a little extra work there after the client release was finalized.  Don't worry about the mismatch, this is expected and is the configuration we tested and validated before releasing.

2008-07-14 Update: Excluding Live Desktop from synching a folder is only possible from the Live Desktop itself in this release, we're working on making it an option you can control from any device in your mesh.  But for now, the steps to exclude your Live Mesh Folder from synching with Live Desktop are:

  1. Create a Live Mesh Folder
  2. If you created it from the Live Desktop
    1. Choose to synchronize it with at least one device
    2. Wait until the folder is completely synchronized on that device
  3. Go to the Live Desktop
  4. Right click on the folder and choose “Change sync settings”
  5. Click the drop down arrow for the Live Desktop and choose “Never with this device”

As mentioned above, keep in mind that only the creator of the folder can do this, and once the folder creator disables Live Desktop synch the files will not be available via Live Desktop for any other members of the folder.

    Today, we have a requirement that you can’t nest Live Mesh Folders.  So if your top level folder is a Live Folder, you can’t make any of its contents into a distinct Live Folder.  We do know that there are some interesting scenarios where this kind of nesting is important, and are looking into how we might be able to support this.

    Sorry for the long delay in replying - I wanted to make sure I had good answers for each of your questions. :)

    1. There's no easy answer to this one without knowing the particulars of your situation, but as a general statement we are working on improving sync speed.  For more background on how our P2P system works check out http://channel9.msdn.com/posts/Dan/David-Steere-and-Trevor-Robinson-How-Live-Mesh-P2P-Syncing-Works/

    2. In a scenario like yours, what we try to do is match up the files that have the same hashes.  This requires the file metadata from the first device that created the Live Mesh folder to be uploaded to the cloud before mapping is attempted on another device.  If you were to map the Live Folder on both devices almost simultaneously you would end up with conflicts, which would explain the folder going away.  Do you recall having conflicts when this happened?

    3. Right now we simply choose the desktop of the user and make sure the name doesn't conflict with an already existing folder.  If it does, we append a number like "001" to it to make sure the folder name is unique.  We use a relative path based on an environment variable to make sure the folder is placed on the user's desktop regardless of drive setup.

    4. Currently Live Mesh is not supported on any Windows Server SKUs.  On Windows Client SKUs that have a Terminal Server component (e.g., Windows Vista Ultimate), the two will function normally side-by-side.

  • Is there a roadmap for mesh?  I would like to find out if there will be a way to exclude certain file types from being sync'ed.

    I would like to use mesh for development where I can exclude any of the user specific files and binaries from being sync'ed to other machines.

  • @ Jayson

    Filtered sync is definitely on our list of features to consider, but we don't have anything to announce yet.

    You may wish to take a look at our PDC website for more information about the kinds of developer ideas we'll be talking about later this year: http://www.microsoftpdc.com/
