The Tech Museum of Innovation in San Jose California (years ago, circa 2008) had a cool station where it would take a pic and send it directly to the app on your phone. It actually was like 7 or 8 cameras in a circle so a group could take a pic together. Unfortunately I don't know the hardware or software, but it could be a lead, maybe you could reach out to them? Good luck. I'm going to follow this discussion, I'd love to find this solution!
