I am not a game developer, but couldn't you make a multiplayer game more fair in this situation by adding artificial lag into everyone's controls to match the highest lag person? Just limit it to a certain amount, like no more than 200-300ms.

I wasn’t considering fairness here (that’s a whole different can of worms). Even for a game where everyone’s lag is the same, X milliseconds of input lag and Y milliseconds of network latency is painful for some values of X and Y. For fast paced games I’d say X is probably just a couple of frames (15-30ms) and Y is about 100ms.
