PopBooth: A Real Photo Booth powered by your iPhone/iPad

Not directly related to this iPhone/iPad app, but I had a lot of fun setting up a simple party photo booth with pretty pedestrian camera gear a few years ago.

Since then, I've upgraded to a DSLR with live preview, HDMI out, and an eye-fi card. So I'm thinking of trying an upgraded photo booth for my next party.

I was picturing an actual booth at a mall where instead of the camera you place your iphone into the camera slot, go into the booth, take 4 pics, get the print and keep the digital on your phone.

This is not a "photo booth", just another photo sharing app. If one were to make a real photo booth (ie, testing / dealing with on-site printing to an ink yet, dye sub, or Polaroid printer), real photo booths are popular at weddings this year. Vendors are currently providing this service for > $600 per wedding.

Does anyone know what company they use to print, perforate and deliver the postcards?
