Thanks. At the moment, it isn't that smart about it.. it is a 
combination of two greedy algorithms. Sometime in the future I'll 
attempt some smarter approaches.

I have done some simple stuff with existing vias and traces, but a lot 
of it requires a re-write of some code, which is just a work around for 
something DJ is planning to fix in the LF work anyway (padstacks). So 
I'm not in any hurry to deal with that.

Cheers,
Anthony
