Our school had a gnutella network on the campus network. It was incredibly fast, and some people were fairly prolific with their content upload reputations. E.g. I remember the highest quality Game of Thrones episodes being uploaded within minutes of them airing.

Though my understanding was that Gnutella worked better than torrents because it was an incredible fast local network, i.e. our campus was connected with the fastest network I’ve ever experienced personally. I don’t think Gnutella works as well over the public internet.
