Is there an open source distributed Bluetooth sound system? Something that lets me distribute multiple rPis (or similar) as base stations around my house and that will
- play one audio stream to Bluetooth devices connected to each station, ideally compensating for latency as needed,
- allow me to roam with one Bluetooth device throughout the house,
- ideally also allow any base station to act like a Bluetooth speaker for my phone?
Does such a thing exist?
