I seem to recall that Mark wanted to keep the CAN-USB simple and  
cheap. Adding space for a Bluetooth module could double the size and  
cost of the PCB. It's not an 8-pin IC.

Is there any reason you can't use the OVMS v3 for whatever you want  
the Bluetooth for? The CAN-USB is supposed to be a single-function,  
cheap, giveaway piece of electronics.
