Can an Android phone be used as a Bluetooth headset/speakers? Is there a way to make an Android phone (HTC Desire HD) act as Bluetooth speakers or headset?

I'd like to use the phone as wireless headphones whilst watching a movie on a computer (running Ubuntu).
As of right now the bluetooth API only supports pairing with the android device as the master.
