If the bt devices are exported in sysfs in the kernel already it is no
longer hal that synthesizes them. Which makes these things much
cleaner I would say.

Synthesizing virtual devices at the HAL level doesn't look like such a
good idea to me, smells kludgy. But doing this on a lower level might
make sense.

But anyway, it's your call, you're the BT guru.

A stable plugin API is not going to happen anytime soon, sorry. Also,
it is not really practical to develop plugins out-of-tree. I
acknowledge the demand for it, but the plugin API is just too quickly

Hmm, I'd love to add proper BT support to PA myself, but unfortunately
I lack the hardware for it. It would be much easier to keep it up to
date for me then.

Hmm, I will try to get myself a bt headset.
