This a neat site. People that are on the tech trail giving television interviews that you can then download and watch. It's like iptv but sponsered by PBS and like some iptv, only available via the internet.
How's this done, bandwidth-wise? Well through the bandwidth sharing, peer to peer client BitTorrent. It's really neat. And the speeds you can get to download things is much faster than some of the speeds the respective servers could handle normally. IE PBS might not have a pipe that can handle hundreds of 1MB connections all at once, but with the miracle of BitTorrent, they don't have to. Cool stuff.
