It's a new year and time for another brand new Windows Live service to show up in beta. This time it's the Windows Live for TV Beta which is described as follows

What it is
Windows Live™ for TV Beta is a rich, graphically-driven interface designed for people who use Windows Live Spaces and Messenger and Live Call on large-screen monitors and TVs. We're still in the early stages of this beta, so many of the features might not work properly yet. That's why we really need your feedback! This beta is in limited release, so you must request access to the trial group. After you’re in the beta, come back to this page and let us know what you think.

You can also find out more about the product on the team's blog at http://wlfortv.spaces.live.com which includes the following screenshot

Hey, I think I can see me in that screen shot. :)
