So I didn't realize that marking my repo read-only to anonymous users, did not mean that you could not view the repo through Beanstalk's web front end.
Instead, you'll need to connect directly to the SVN repo. To do that, you can either connect to the SVN web UI, which is ok (you can use a download agent to leech the whole folder tree, or you can use an SVN client (I use TortoiseSVN). My main repo is:
http://davidlem.svn.beanstalkapp.com/windowsazure/trunk/Windows Azure Hacking
In there, you will find the following directory structure:
PhotoStore and Windows.Azure.Storage.Blobs contain the source you need to get the PhotoStore blob sample up and running. There are other projects in there too, feel free to take whatever you like, it's all sample stuff.
