Homebrew PCBs

I'm finding John's idea pretty intriguing.
Just to take the brainstorming another step: 
One big problem with PCB routers is tool life and their cost.
But using a CNC router with a cutter to just cut through the surface of the
resist and a thou or two in to the copper would prolong the life of a
carbide tool immensely... and produce a board that should etch quickly and
cleanly.
Yes it would be better do away with etching all together but a marriage of
the two technologies for some applications could be useful.
