This used to exist in 2008 and it was perfect. It was called Joost and worked like this: - P2P streaming - You get a big menu of channel logos - You click on a channel and it would start the first episode of a randomly chosen series from that channel, or it would continue from where you left off - There might have been a "zap" function? I'm not sure - The GUI was so nice and large that if you connected a Wii Remote to your PC, you had the best TV experience from your couch, ever: Just press a button to bring up the menu, aim at the channel you want to switch to, done.

Such a shame that it failed, nothing after it ever came close.
