I saw it mentioned in the BitTorrent/streaming thread, and then I got invited by a friend of mine. It's still in its beta stages, but they've just signed a deal with WB and it looks set to be huge. They already have deals with Much, Alliance, Aardman (Wallace and Gromit) and a bunch of other people.
For those of you that don't know, it's on-demand streaming TV in high quality by the guys that made Skype and, previously, Kazaa. The download on the thing is about 6MB/minute, which, for the quality it offers, is actually pretty damn impressive. I know one of you's already contacted me for an invite, so how about the rest of you? does it interest you at all?
