As handy as services like AirDrop or Android Beam may be for shuffling content between nearby devices, they're platform-exclusive. That's not much help if you want to share photos from your Android phone to an iPhone, or vice versa. However, Google may soon overcome that barrier. Android Police, Techaeris and GigaOM all have evidence of Copresence, a service that would let Android and iOS devices swap content over WiFi. Reportedly, it uses location data (including Bluetooth) to set up the connection; after that, you can send directions, photos and other info without having to either bump devices or rely on cloud storage options like Google Drive or Dropbox. The technique shouldn't require a Google account, either.
