Is there anything like Microsoft Sync for the home or media center computer?

"I think the issue here is that the Windows Bluetooth Stack (Broadcomm / Widcomm) does not implement the HFP Bluetooth Profile used for Hands-Free Telephone stuff (at least what I coudl gather so far).

There is not much information on that topic anywhere to be found, but I'd really love to be able to telephone with my PC headset instead of having to switch to a different headset when answering a call."
