Since the M2 has a RS232 control interface, what about some sort of 
cheap box that reads a pot and spits out the appropriate control message.

There are such thing floating around out there on the web.  Look at 
robotics sites or mechanical gadget/animation people.

Kind of like the R/C servo testers that have a pot and a 555 to generate 
the 0.5 to 1.5 ms pulses  a servo wants to see.
