McQuary limit = M = meatware

meatspace /meet'spays/ n.

The physical world, where the meat lives - as opposed to cyberspace. Hackers are actually more willing to use this term than `cyberspace', because it's not speculative - we already have a running meatspace implementation (the universe). Compare RL.
