Joost - the future of internet TV?

First these guys brought us Kazaa, if that wasn't enough they came out with Skype - and now they have unveiled their latest secret project...Joost.
Supposedly the next big thing in "onlineTV" Joost will provide high quality full screen TV over the Internet and surround it with online features such as chat, communities, targeted adverts, search capabilities etc. From the screen shots I have seen it looks impressive - I have applied to be a beta tester but have yet to receive my token. Keep your eye on this one, and throw your TV away.
