gerbv has basically a notion of vectors and this seems like more of a 
graphical problem. I am in the favour of one program solves one problem. 
The solution would might be some plugin API in gerbv to expose the 
internal data structures, but it is currently in the idea stage. Anyone 
wanting to hack some gerbv is always welcome on the gerbv-devel mailing 
list.

When you have placement information available in your program it would 
seem like a great idea to support that.

There is an european PCB vendor that supports one "free" CAD, you send 
your design in the format used by that CAD program and they makes your 
PCB from that. So to accept designs "that" (not to be mentioned) CAD 
program and/or PCB could give a slight competing edge and you don't have 
to cross the river to get some water.

Just my 50 öre...
