It depends if he speaks of the mob/players/NPC view distance or the terrain/landscape view distance.
The first is server side (so everyone see the enemies at the same distance), the second is purely client side.
I think pushing the setting further than the maximum (777, it was increased from 777 to 1277 in WotLK and furthermore in CT) requires modifying the client. It's not allowed, and even if it was, I don't know if it's possible (but it probably is as Machinima Tool succeed in later versions).
