I’ve been playing with Live Mesh for a long time now, and have been loving it. During this time I’d been hearing about applications for Live Mesh, and while it sounded interesting in theory I didn’t really get what the point would be.
Then I watched this video:
The video walks you through the development process of a Live Mesh app. The “whoah” moment is when I realized that the one codebase - without any special code - created an application that ran identically on the web and on the desktop. Money shot starts at about 25:30; but it helps to watch the whole vid.
This is fascinating; this is a “Web OS” (I hate that term).
