Transfer of data-intensive content between portable devices

A first portable telephone, comprising:

• a receiver component that receives an indication from a proxy server that a second portable telephone is estimated by the proxy server to be in wireless communication range of the first portable telephone, and that the second portable telephone has requested a peer-to-peer connection with the first portable telephone;
• a power controller component that causes a wireless radio to be provided with power responsive to the receiver component receiving the indication from the proxy server;
• a connection establisher component that establishes the peer-to-peer connection with the second portable telephone by way of the wireless radio;
• and
• a file transfer component that causes at least one file in a data repository on the first portable telephone to be transferred to the second portable telephone by way of the peer-to-peer connection responsive to the receiver component receiving a selection of the at least one file from the second portable telephone, wherein the at least one file is labeled as being shareable in the data repository.

A computer-readable data storage device comprising instructions that, when executed by a processor, cause the processor to perform acts comprising:

• transmitting a profile to a proxy server by way of a cellular network connection, wherein the profile identifies a user of a first portable telephone and is indicative of shareable content on the first portable telephone;
• transmitting data that is indicative of a location of the first portable telephone to the proxy server by way of the cellular network connection;
• receiving an indication from the proxy server that a second portable telephone has requested a peer-to-peer connection with the first portable telephone, wherein the second portable telephone is predicted to be in Wi-Fi range of the first portable telephone;
• responsive to receiving the request, powering on a Wi-Fi radio in the first portable telephone;
• receiving an IP address that has been assigned to the first portable telephone from the proxy server;
• receiving, by way of the Wi-Fi radio, a request directly from the second portable telephone to establish the peer-to-peer connection;
• establishing the peer-to-peer connection responsive to receiving the request from the second portable telephone;
• receiving a selection of at least one file on the first portable computing device from the second portable computing device, wherein the at least one file is marked as being shareable with a user of the second portable computing device;
• and
• causing the at least one file to be transmitted to the second portable computing device by way of the peer-to-peer connection.
