Sopcast - free internet T.V.

Hey, I recently came accross this little thing, I used internet T.V. a few years ago when cable went down back home, it's improved GREATLY since, well anyway there's this one in particular called Sopcast which can be found on sopcast.org you have to download the player (which is free of ad/spy and all the sort) and then you have access to quite a few free channels.
It works on a P2P base to my knowledge and well, it has a WWE channel that shows all sorts of matches, new ones, old ones, Pay Per Views (not live) all for free. It also has quite alot of sport channels and I've been catching the world cup on a few of them when I'm not near a T.V. but near a PC.
So I was wondering if anyone uses this or any other form of Internet T.V. I think there's a BIG future in this thing, a BIG one.
