Staying in the same room, I went to svl: Peer-to-Peer Subversion Over Bonjour, by Artur Bergman and Léon Brocard. Okay, okay, I'm being a little cheeky: I presented that talk. We talked about the history of version control systems, concentrating on svk and introducing svl. It wasn't that packed, but we had some intelligent questions and discussions and everyone seemed interested. Check out the slides (PDF).
