Abstract: Described is a technology that uses a web service as a proxy for transferring data between mobile communications devices. A short range communication link is established between a source device and a destination device. The source device sends a content identifier over the short range communication link to the destination device, that the destination devices uses to access the content, including when the short range communication link no longer exists. Also described is security for the content via authentication data (e.g., credentials) and policy associated with the content to control its access. The source device may select the destination device or may broadcast the content identifier to any number of destination devices within range.
