My rigs are all stereo, but more to accommodate asymmetrical rooms than to pan stuff.

So its dual-mono, not stereo?
I'm surprised at the amount of definition bending in this thread.
Stereo is when everyone can hear BOTH the L/R at roughly the same volume & time (I do not have an answer for how many ms is considered same time, is it related to haas, something else, etc)
Mono is when everyone only hears ONE source
Dual mono, exploded mono, whathaveyou - is probably what most are doing. It's what I'm doing. I 'can' send (pan) a different mix to each main speaker. Most things are mixed mono because each main is only covering its own area. I still run stereo sources into the system and typically hard-pan the sends because of they typically aren't very wide stereo sources (meaning even hard-panned there is plenty of 'mono' content so no one is missing the other main/side).
But on the off-chance, the room is narrow and long and both speakers can adequately cover the entire crowd then that opens up the potential for nice stereo mixes/setups.
