Another interesting programmer!

He's invented BitTorrent (http://bitconjurer.org/BitTorrent/) - which is a kind of P2P file sharing network for distributing very large files.

Similar to work I did for a company called PushTV - except that was a centralised model.

He seems to be good at inventing things - including a source control system (even though he also uses CVS!)

He uses mainly Python, and talks about Extreme programming.
