I love this idea! In the PHP community we've started to have more and more talks show up on the conference circuit about getting involved, but this is even better. I bet in every major city there's people who would be interested in getting involved in open-source who aren't going to go to a conference just to find out, but they might spend a day or two some weekend doing just that.

I can't wait for the material for this to come out. It'd be great if it was on GitHub or some similar service so we there's an open source way to get people into open source.
