I think it would be pretty great exposure for bitcoin, if someone knowledgeable about the internal workings of bitcoin were to submit a proposal to OSCON 2011 (
http://www.oscon.com/oscon2011) for a talk about bitcoin. The place is full of all kinds of FOSS ethusiasts, and besides the costs of making your way to Portland, Oregon, USA, it would be completely free (I think).
So... anyone up for it? Gavin, Jgarzik, Theymos? Bueller?
