This is very cool stuff. Justin.tv (link below) is a site that allows people to send in live streams from their phone or other device directly to the net and you can watch. One channel had a football game that was blacked out locally that was sent directly from a guy in another area. It also has online chat, so you can share comments with others about the show being played live.
It has multiple feeds and I can see foresee family events for the holidays, where a few people in different cities show live video and add comments. What a great way to keep in touch and better than picture phone. I made need to upgrade my phone to play with this one.
