haven't tried it, but a wire map with nos. assigned to each pin
and then resistance checks should do it.  You'd have to have the
board empty, but then you could use a conductive brush to speed up
the "scanning" process and once you finished with an area you wouldn't
have to go back, so you would begin to eliminate portions of the PCB.

Can't see why this wouldn't work with any no. of layers
