Is anyone currently working on adding these missing pieces (third party
or Apple)? What underlying plumbing is missing for SCO? Is this
missing plumbing hardware, software, or both? If all the hardware is
there and no-one is about to release the missing software, maybe I can
get to work on it. I've implemented protocols before, from OSI layer 2
on up.

SCO is the isochronous link which is used to support headset audio
over Bluetooth. This would be quite difficult for you to add to the
stack, since the underlying plumbing does not exist at this time.
The other portion of telephony is TCS-BIN. There is no stack support
for this protocol per-se. However, TCS-BIN uses an L2CAP channel for
it's data side. There are L2CAP APIs so you could add support for the
data side of TCS-BIN. In a quick look at the spec, it appears that
TCS-BIN also requires the audio link to come from the same device, or
at least it implies it. You may have luck using just the data link,
or you may find that phones expect there to be a corresponding audio
link to go with the data link - I am not sure on this one.

I have an Ericsson T68 that I'd like to integrate with my Powerbook.
