According to the little board sitting on his table at other Cons, you can get autographed polaroid or you can take a picture with your own camera- at the table. Many of the photos were taken at the table. I've also seen several that seem to have been taken while people waited in line. (That might pose a problem- if you're caught.)

Thanks Monica for answering in such detail. Read on Zoom's board that he's doing a panel on Sunday. Can't confirm that on the DragonCon website, so I'll find out where the girl who posted that read it. I can only go for a day and if he's doing a panel on Sunday, I guess I know which day it will be. thumbsup
