Here at Caltech, Prof. Rutledge et. al. have developed some neat E&M
analysis software (IBM-PC) that I think is just what you want.  Just
the little bit I'm aware of allows you to analyze transmission lines 
with both distributed and lumped impedances and generates Smith charts
and transfer function plots.  I imagine they'd let you have a copy.
