No, I have not had time to do the sink.  There is another option I was
going to try.  Pulse has an asynchronous interface that is much better
than the simple interface.  I still think the sink method would look
better.  The simple and asynchronous methods both require that you use
the "dumby" sink.

Not sure but I think not.

That is absolutely possible.  xrdp-chansrv has a unix domain socket
for each session
/tmp/xrdp_chansrv_audio_socket_10
/tmp/xrdp_chansrv_audio_socket_11
/tmp/xrdp_chansrv_audio_socket_12
one for each session.  You can connect to it from any process that
user runs and send audio data.
Pulse just seemed like a logical first step.
