while all this is technically possible, it would be good if you can give
some more detail about use cases. See below for inline comments.

If you wan't this e.g. in a voip application it could create a second
alsasink using the bluetooth headset when the headset gets connected and
switch them on-the-fly. It could keep the old sink to switch back later
if needed. It certainly makes a good testcase for gstreamer :)

can one use dmix via a bluetooth device? Gstreamer provides mainly
interprocess stuff.

What is the problem with a bluetooth headset appearing as an
alsa-device? Imho this is the way to go and then use gst on the
appliation level.
