Where the effort of doing a conversion would be more appreciated, at least 
from my side of the fence is in something that could convert the copper 
patterns gEDA can make, directly into an RS-274-D format, making it simple to 
lay out a double sided board, and do it on the mill by removing the unwanted 
copper.

Humm, ISTR a was utility called hpgl that I used to run on an amiga, which 
could filter the output of the amiga pcb design proggy whose name I've long 
since forgotten and drive a printer to make the exposure mask on transparency 
film.  From that, it seems to me we ought to be able to take the guts of 
Peters POTrace and generate the gcode for a given layer and carve it.

Has anyone done any work long those lines?  I keep getting sidetracked with 
the real world of late it seems.  Malfunctioning tv transmitters and such.
