Microsoft's blog/IM/chat search with a TV interface, Windows Live for TV, has entered into beta. It seems that the former Project Nemo has gone live in the last week or so, and was spotted today by the folks over at LiveSide.
The interface allows users to search Windows Live Spaces blogs, either with keyword searches or through gallery views. users can also use Messenger and Live Call via a remote-control interface. It apparently won't work with Windows Media Center XP, but will require Windows Vista Home Premium or Windows Vista Ultimate RC2
