I know about Fastcap and Fasthenry .. from MIT I think.

There's also "atlc".

There are simple formulas that work for some cases.  If you 
don't want to model coupling, they are good enough.  To really 
model coupling you need a field solver.

The biggest block to having it for PCB is file format 
translation.

Don't know, but the licensing is not appropriate, so I am not 
going to bother to find out.
