I think designing the tool up front to explicitly deal with and support 
2 different back end flows (layout and simulation in this case) is very 
important.  Presumably that will be a good vehicle to making sure it can 
extend to many back end flows.  I think that is the only way to go, 
otherwise you end up with a real headache trying to make simulation 
netlists work right and maintain decent footprint selection.

absolutely.  In my mind this tool has a very small and well defined api 
to communicate with pcb (or whatever else) about footprints but in 
general knows as little as possible about the details of what the 
footprints are and where they came from.
