BlueZ will take care of the signalling part only, it is not
responsible for streaming anything, so if you expect that by just
connecting 2 headset it will start streaming to both than you are
looking in the wrong place. Android seems to use a library iirc
liba2dp which is responsible for streaming, you should probably have
to change it to be able stream to multiple devices simultaneously.
