Folks were using AirDrop to send anti-communist files or posters to others in a short range, resulting in a crackdown by the Chinese government on AirDrop and bluetooth file sharing. I believe Apple complied and implemented a 10-minute cool down on file sharing with strangers. I wonder if such a product could help them mitigate this. We could make it open source and make it very DIY friendly in case it cannot be sold.
