I find Vxiaocheng's use of QR to be super interesting and something that I'd think is worthwhile to work on; QR reading is now native in android + iphone camera apps and this is an itch I've been looking to scratch for a long time. Anyone interested? I would think of expanding the application to restaurants, libraries, etc. I would be comfortable with design + engineering + product while mostly looking for a business developer to sell the product to customers.
