I just got out of the Tor hack day in Cambridge MA (which I hear may become a monthly event, yay!). We divided into two rooms: soft ware (code) and soft skills (documentation, policy, how to run a server on your PC, fundraising,...)

I thought this worked pretty well, although I can't say either room was lacking conversation! But in our case this is also about community building for an open source project - slightly different agenda.
