I think that a parser for spice can be written by an average computer
science student with some spare time (very difficult to find) or by anyone
who has experience in the field in some months. The main issue is that
before writing a front end, a back end would be a better choice. 

When I say a back end, I am thinking ngspice as a set of independent
execution units with interfaces, and a back end that link them and
sequence their operations.

Michael, please pay attention to the new Resistance code, it will
understand ac and dc resitance values ala HSPICE
