Yes, probably several ways. 
1) PC behaves as a bluetooth headset, no changes needed on moko.
2) IIRC someone has already done dbus message forwarding over the USB 
connection, which would give the computer access to the FSO API. You can 
certainly forward X over ssh and display the app UI on the connected computer, 
or use VNC to take remote control. Audio forwarding by bluetooth/esd/pulse.
3) Configure asterisk on the moko so that it does what you want. This would be 
an extension of Nicola's work on making asterisk a VoIP client and possible 
answerphone on the moko. Connect to asterisk using a SIP or IAX client on the 
PC, and initiate/answer GSM calls through it.

I think there's already an app to do 1. I might be tempted to look at 3 but 
probably not in the near future.
