I would love to get a BarCamp organized specifically for bitcoin developers, and layered app developers. I would propose to have it in the Boston/Cambridge area where there are many brilliant entrepreneurs and developers in the MIT and Harvard communities.
A BarCamp is an "unconference" at which the attendees determine the agenda on the morning of the event. There are no big name keynotes, anyone can propose and facilitate a session and the costs are very low or free if appropriate sponsorship can be obtained.
