Live Mesh rocks
When you get a chance, check out Live Mesh at www.livemesh.com. As it is right now, it's incredibly useful for sharing files across computers and users. For example, I synchronize certain folders across both of my work PCs and my personal laptop, so that I can access those files anywhere. I also synchronize a couple of folders with my wife's PC, so that we don't have to email the family budget back and forth to each other anymore ... we automagically work on the same document. With 5G available for the free preview, you can also use it as a simple way to back up a lot of files - automatically.
What's even more exciting to me as a developer is that Live Mesh is a platform ... the existing functionality just skims the surface of what is possible. The platform SDK isn't released yet (or even available to play with), but moving forward, Live Mesh will give developers the ability to create rich client applications that store their data in the cloud and automatically synchronize across devices - even mobile devices. I have a couple of ideas for this already ... can't wait to see what other people come up with.
