A friend was kind enough to send me a Joost invite a while back. I have been playing with it and it's pretty cool. It's like video on demand over the Internet. I don't know how much I will really use it, compared to "real" TV... but Stinky has been enjoying watching old episodes of Rocky and Bullwinkle.
It's still in beta... but if you are interested in checking it out and would like an invite then let me know!
