quinn posted quite a bit here on apug in the past. I think he moved to Germany, or something. i haven't seen him on apug in a long time. last i knew he was doing workshops and working on a DVD. i don't know where the DVD sits now. maybe others have more info for yah.
Quinn has been rather busy lately, but he's still active on his own site - www.collodion.com - and forum. His forum is by application only, since he was too busy to deal with spammers full-time.
Apologies in advance, but every time I see this topic pop up, my warped mind thinks "Wow -- must have to use a real-l-l-ly slow frame rate to do video with wet plates."
