I finally got my invitation to the internet TV service Joost (http://www.joost.com) from the people behind Skype. I have to say I'm very impressed. Software is nice and easy to use and the quality of the video streams is really good and uses a ridiculously small amount of bandwidth.
There isn't a huge amount of content yet but I think it's only a matter of time.
I've been using it for a few days now and already have 2 invitations to give away. Let me know if you're interested.
