Well, the chip reverse-engineering isn't all that tough actually.. Just need
access to a diamond cutter that goes through the layers one by one, about a
few microns at a time, and a microscope.. It *might* even be possible to do
it with a CNC mill.You can figure out exactly what the content of the chip
is that way.. It really doesn't take all that long. You take one picture
after the next then merge them all. Not more difficult than reverse
engineering a pcb using the same method of shaving off layers.

The guy I work with right now used to do it for a living! What a waste of
talent though, since right now he is lucky if he is allowed to solder
together 2 wires.
