Apple has shown interest in improving device discoverability and local networking using existing technology like RFID, Wi-Fi or Bluetooth, or even a new proprietary wireless method.



From Apple Insider:
The details come from Apple's latest patent application, entitled "Local Device Awareness," and discovered by AppleInsider. The document, made public this week by the U.S. Patent and Trademark Office, describes a number of electronic devices within close proximity being able to automatically communicate with each other and share information with minimal to no user input.

Apple notes in its patent application that while networked devices can communicate with each other over great distances, communicative proximity is not equal to physical proximity.
