   Stating the obviuous...
   How about this kind of situation. Let's say you are designing low-pass
   filter for mono signal and you have readily world's best quad opamp on
   your part box and symbol is there and SPICE model is there. Due to case
   you need to use slot three to fit all the resistors and caps because
   there is space on the enclosure. With this situation, there are two
   schematics. One for spice and onether for pcb.
   Ofcourse this is hobby example and gEDA should be considered
   professional tool :) But are those commercial situations so far away
   from that?
   I don't think that it is too hard to add the modelfile attribute for
   symbol, since it can be anywhere in the system.

   I really liked DJ's ideas. I wish I was able to help, but gEDA is still
   too far away from my skils.
