Well, I can't figure out what's going on.  I pulled the caliper off 
the car, and tried pushing the piston in, and ended up breaking the 
tool in the process(plate shaped like a pad, with a screw in the 
middle); tried rotating the piston, with no luck(and I don't see any 
allen key hole; just two opposing V-shaped notches.)

I've also tried pushing the piston in with a C-clamp; no movement whatsoever.

To make matters worse, after my manipulations, the piston is now 
leaking fluid in a slow drip-drip-drip.  Right near the end, looks 
like where the boot attaches to the end of the piston.

I suppose at this point I have nothing to loose from completely 
removing it from the car, "benching" it and ripping it completely 
apart; I wanted to avoid that, but it's either overhaul it or replace 
it with a rebuilt, and either way, it's gotta come off...<sigh>.
