(I thought "RockBox community seems cool feet" meant that Rockbox (collectively) was "cool with it," but them having "cold feet" makes more sense...)
A few years ago, I think Rockbox starting thinking about the newer DAPs that had a bluetooth device and they talked about adding a bluez stack so the DAP has an additional secondary purpose to feed bluetooth speakers. I do not know if a Rockbox developer went all the way in implementing this to the end.
