One place where this sort of thing would be very useful -- if it's not already being done, is scanning old optical soundtrack films that have shrunken or edge-decayed so they don't work reliably in a sprocket drive. Perhaps there's some rubber-roler way to feed them through a scanner and then "play" X number of sprocket holes per second or some other means of playback. Like I said, know Hollywoods brains and deep pockets, this might already be out there and in use.
