I agree. And it would even be nice to use a bluetooth headset to do
things like speech recognition or dictation. I am assuming the same
support would need to be built in.

This is actually something that I have been seriously thinking about
too... I'm nowhere near the level of skill required to be able to code
parts of the bluetooth IO stack, but I do know that if such facilities
were available, it would be a wonderful addition to the fantastic
capabilities already available. One of the first things anyone who
uses bluetooth with their computer asks is 'how can I use my bluetooth
headset / internal mic as the input to my phone?' (me being one of
them and a Win XP user I work with being another).
There would be some serious WOW factor to being able to click 'accept
call' when AddressBook.app informs that a call is coming in and then
using the computer's audio in/out to take the call...
Just my 2p's worth

What I can tell you is what is missing from the current
implementation. Currently the Apple HCI controller driver does not
open any of the SCO pipes to the USB device, so this is the major
missing piece.
Additionally, there is a hardware question to answer before you know
if support will be possible with a given dongle. Some Bluetooth
silicon will support SCO with the audio being piped across some
external HW codecs and ports, which are not available on the USB bus,
where others will provide access to incoming and outgoing audio data
over the USB interface.
So what is needed from the Bluetooth perspective is the addition of
code to open and read/write the isochronous USB pipes on the
Bluetooth dongle married with a USB dongle which can support the
audio data piped over the USB interface. On top of the Bluetooth
pieces that are missing is the code needed to pipe data into and out
of the Mac OS X audio system. I am not very familiar with the audio
system, and how to write drivers in that world, however that
information can be found at:

Is anyone currently working on adding these missing pieces (third

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.
