Amusing idea: conceal a flash chip in the film cartridge and record video to it from the camera used for the viewfinder. Put in a sound generator to make clicky film advance mechanism noises when taking pictures. The film in the cartridge is just a dummy and is not exposed. When the film cartridge is mailed in for processing, download the video, run it through Filmlook to give it grain and jitter, then upload to the cloud server. If the user orders the "return processed film" option, print the video to film stock at the processing plant.

No hipster will even notice. :) If done right, it will be even hard to prove there was cheating in the process.
