well, jack2 will listen to dbus already (see the link to robin's work on
this). jack1 is never going to interact directly with d-bus in the same way
as jack2, but for this particular purpose, a platform centric patch would
be smart.
better yet though, this should be buried inside the ALSA backend and all
backends should have a way to tell JACK that the device has "gone
away".we've had to visit+revisit this for the new abstracted audio I/O
backends inside ardour already.
chances of any of the usual suspects doing this for JACK1: close to zero i
think.
