I'm on a very small college campus where they graciously block every port except for web and a few other app ports (iChat video doesn't work, SMTP ports are blocked, and of course bit torrent doesn't work). I can usually get connected to the tracker, but no peers ever connect. Now for those who may chastise me for using bit torrent, I'm downloading a video my friend made in the US, so there is no legal aspect to this. Any idea around this scourge of port blocking!?
