The customers would usually have access to a PIC programmer - both the 
equipment and the person - of some kind and would get a hex file, 
probably by email or from the web.  I can't mandate a particular type of 
programmer.

I had hoped that there was some easy way of embedding a number in the 
dsPIC and not overwriting it when firmware is changed.  The ID is really 
for traceability.  Sadly, the dsPIC has no EEPROM.
