I went to a meeting of the Irvine Underground (irvineunderground.org) which reminded me of late-90s SF CP meatings. Although the overall tech level was probably lower and social implications weren't a big topic. Also, at this meeting, there were far more cameras or videocams than were present (at least overtly :-) at the few CP meats I attended. However, nyms were used more than they were (overtly :-) at CP meatings; this may have been due to a "introduce yourself" poll. The IU group seems to be a bit more social, going to movies for instance, than the topic-only CPs were. The meeting was held in a room at an IHOP (pancake restaurant for furriners) The exploit mentioned in http://www.usatoday.com/tech/news/2003-12-11-microsoft2_x.htm was demonstrated, we were debriefed on the recent LA 802.11b War Flying mission (and the EMI resistance of 1960's era single-engine airplane instruments :-). Toorcon organizers were present. About 30+ people were there, with what appeared to me to be a bimodal distribution of skills, some advanced, some admitted unix newbies, etc. There was even recreational lock picking. A WiFi LAN, net connectivity through someone's cell phone eventually. A video projector. I didn't notice persons with exceptional Euler numbers, though black was definately the color of choice for garments. Ages appeared well distributed from undergrad to hoary. One gent noticed a certain TLA on my cypherpunks T-shirt and admitted that he had once worked in Ft Meade, though he wouldn't say on what :-)
