Actually we've been through pretty much everything you've said. LH's transducer 
suggestion sounds best, ideally vibrating the bridge up and down, but if that's 
impractical it would vibrate the body at the point the bridge rests on the 
body. It's not a problem if the transducer makes some sound itself, as it is 
supposed to sound like a bowing string, but if it can't be heard the 
synthesized string bow sound can be mixed in anyway.

>>Also, as someone else said, watch out for the soundpost inside the body; it's 
not glued in place, and if you remove the bridge it can fall out, reducing the 
resonance by more than half and weakening the top of the cello so the tension 
on the bridge can crush it.<<

I saw that warning and that just doesn't seem like a proper design. In fact I 
always thought the bridge just sat ontop of the body, held there only by the 
pressure of the strings. To have the inside of the instrument fall apart if the 
bridge is removed sounds ridiculous. But it's something to keep in mind for 
sure.

>>I've mentioned this before, but I have a book called "Synthesizer 
Technique" .... Moog has a couple of articles on using filter banks to simulate 
the resonances of string instrument bodies.<<

I scanned the Moog string simulation article and posted it to the list a couple 
of months ago. So anybody who was interested should have it.
