This p2p system does not work well for streaming-video, i'm assuming, because the downloads are higher than the uploads. I mean, if people can only upload at 50K/sec, but they need to download at 100K/sec, it would be difficult to achieve a quality stream. But with GTV, because you only need like 10K/sec down, the upload amount far exceeds the download. Unless you're on dial-up, you can easily provide more than 10K/sec up.

If this technology was adopted for GTV, it could provide perfect quality video, at no server-cost. It certainly wouldn't bother ISP's, or choke their networks, because the overall amount of bandwidth is so small.
