Will the client's or the server's VISIBILITY setting be used during multiplayer games?

I'm sure many a cheater would love their own VISIBILITY setting to take effect, giving them a terrain viewing advantage over opponents with lower settings. Fortunately that's not how it works. The server's VISIBILITY setting is what's used. If the server hosted MP mission has SETVIEWDISTANCE defined internally within the mission's script, then the SETVIEWDISTANCE value overrides the server's VISIBILITY setting for the duration of that mission.
