I'm sure this isn't available, because if it was I would imagine it would be quite popular. But...

Is there any software available that will allow the calls from my Treo to go though my computers speakers and microphone; basically using my computer as a bluetooth headset/speakerphone?
I don't know anything about how it would work, but It seems to me that the software would need to emulate a bluetooth headset signal.

Anyone got any info about this???
