ProxToMe, for iPhone and Android lets you discover people nearby by leveraging Facebook to share digital content in real-time. By using a proprietary wireless technology the app detects users within 250 feet and allows for seamless interaction. Following on the heels of their iOS release, it now supports Android.

The app’s requirement that nearby users also have it installed makes for an interesting chicken-and-egg problem. Launched in time for the annual SXSW Interactive social computing blowout, ProxToMe appears to be hoping for an initial boost from bands leading the way with content sharing.

ProxToMe also enables cloud-to-cloud content sharing, including Dropbox to Dropbox, which neatly sidesteps mobile bandwidth issues.
