We are using Bittorrent sync as part of the Playnode system for DJs to provide background music in businesses. This project is in beta, about to launch on Kickstarter. The audio hardware is a raspberry pi. Video demonstration: More details: https://control.neilscudder.com/about We hope to develop desktop applications to streamline the process using the API if the Kickstarter campaign is successful.

Keep up the great work.
