...Heck, I didn't even know they had a clue how to do it with any particle *other* than a photon.

BTW, have you or any of y'all read "Surely, You're Joking Mr. Feynmann?" Its the memoirs of Dr. Feynmann, a Physics professor who won the Noble Prize, some great discussion of Physics and his experiences at Los Alamos, but the reason to read it is because he's a kooky, arrogant and funny guy. Very interesting read.
