This is really cool, i was watching Mr.Magoo episodes over the internet using Joost, which is an internet TV service provider created by the founders of skype.com
from Wikipedia
The program is based on P2PTV technology and is expected to deliver (relaying) near-TV resolution images. It turns a PC into an instant on-demand TV without any need for additional set top box. News updates, discussion forums, show ratings, and multi-user chat sessions (often linked to the active stream/channel) are made possible through the use of semi-transparent widget overlays.
sounds like a step forward in IPTV revolution to me
