Generally, though, this is a gschem issue: how do we devise symbols and attributes that represent what we want? Do we need changes in the core (I hope not)? Translation to the various layout and simulation tools is then a job for gnetlist or xorn. Pcb, having no mechanism to do anything with this data, isn't terribly relevant at present.

I believe this could be done easily with computational geometry line sweep algorithms and placed in libgeda for all applications to use.
