If you want to know where Microsoft is taking your home, you might want to check out the videos of Home Server from the PDC (Professional Developers Conference). The specific video is Developing Connected Home Applications and Services for Windows Home Server.
There are some pretty exciting things in there about automation that will control your heater, air conditioner, blinds, TV, and the list goes on.
On the second day of PDC, CJ talked again about Exposing Connected Home Services to the Internet via Windows Home Server. Near the end, there is a bit on Windows Live Mesh, that I commented on earlier this week.
