Still just a beta, this Windows Live Media Center plugin allows MCE owners to use various Windows Live services from the couch. Working with Vista, Windows Live for TV lets you browse your friends Spaces—kinda like their blog/MySpace—and call or IM your friends via Windows Live Messenger.
Code named "Orbit", this project is still beta and thus, still flakey. If you want to try it out, you can sign up for the here. All you need is a Live account, Vista Home Premium or Vista Ultimate, and a mouse, keyboard or remote. There's little practical use for this—why not just use a computer—but makes for a neat plugin for people who enjoy social networking in the living room. Weirdos.
