[MUD-Dev] Quake II has gone GPL

Or, in Everquest's case, both clients do collision detection, which
the server doesn't validate, and, depending on the lag, B may either
block or not block A.

This looks stupid, from a theoretical point of view, but it usually
works (i.e. A and B get to see a "correct" situation, in which
either A passes before B manage to get to the door, or A is blocked
by B).  This only fails if lag is major and the situation borderline
(they rush to the door at the same time).
