title: Proximity detection with Bluetooth LE and iOS
body: <p>I've been investigating Bluetooth LE a bit, especially after reading some rumors apple may be implementing some sort of "iWallet" for payments using this technology. For those more fmailar with the technology, could I use it to painlessly connect to devices together by moving them really close and hitting a button without the hassle of pairing? I.E, if i want to send a file to my friend who's next to me.</p>
