xev shows me different scan codes and key bindings for left/right
shift, cmd, and option. Control is swapped with caps-lock on my
machine, but I'll bet I would get separate codes for Control_L and _R.
This may have changed since Tiger -- I seem to remember not being able
to distinguish them before.

BTW, if you really want to go nuts with keyboard remapping, look at
the event taps API. I wrote a 100-line program that swaps ctrl and
cmd in Terminal.app (and *only* in Terminal.app) without any code
injection, input managers, or unsupported APIs. You can just as
easily do system-wide filtering. My modded my code and wrote a filter
that remaps the numeric keypad to match the space numbers in a 3x3
spaces layout (1 2 3 on top, 7 8 9 on bottom), and it only takes
effect if the ctrl key is held down. Fun stuff.
