Learning process and test, if you're smart, can be done in 4h total for Technician. There are lots of programs to do it in 8h, but IMO a tech person should be able to do it in less time. I used http://www.baears.com/ to do tech (and then studied for General during the rest breaks and got General at the same time!); it's a good choice in the Bay Area.

I should be an Extra and a Volunteer Examiner myself in a month or so, so along with 2 friends with Extra/VE could run classes. I'm planning to do crypto meetups/keysignings/etc on the Peninsula on the first friday of the month anyway (5-10pm somewhere in MV or PA, probably near Google, nominally a 2600 meeting), so doing ham exams during that would be fine, if people studied before that.
