i have the sco support code in my local cvs. so far i managed to receive 
audio data from my plantronics m2500 headset with 3com usb bluetooth 
dongle. i will give it a little bit more polishing and testing and then 
  commit it to -current. it probably would not make it to the 6.0 release.

what exactly are you planning to implement and how exactly would you use 
headset and handsfree profiles on freebsd?

i never said freebsd can not do it. what i said is that i did not know 
how to do it. fortunately, i figured it all out. it is not very obvious, 
but after playing with it for awhile i managed to teach ng_ubt(4) to 
receive sco frames via isochronous transfers.

thanks,
