DoubleTap: share music between Android phones by tapping them together

Jon "DVD Jon" Johansen sez, "At Google I/O today we launched doubleTap, an update to the doubleTwist Android app that adds proximity-based sharing for NFC-enabled Android devices such as the Google Nexus S. With doubleTap users can transfer a video or a song simply by tapping two devices together. NFC (Near Field Communication) is used to initiate the sharing and then the actual file transfer happens over WiFi or Bluetooth. We are demoing this powerful feature at our stand at I/O using some great Creative Commons licensed tracks from ccMixter. In this app update, we also brought AirPlay support to Android so now you can stream to your Apple TV from non-Apple devices!"
