bluetooth voice connection to OS X?

[Myles Uyema]

Was wondering if we can somehow interface OS X as a voice connection to a 
bluetooth phone.  I've already used iSync, addressbook dialing/answer, 
modem connection, and file swapping.

So my Mac has a microphone and speakers...can I somehow connect to my 
phone with bluetooth voice service as well?  It'd be a pretty cool method 
for a 'speakerphone' feature.
