Also, I'm not sure if this is a problem with MPMPM or mods in general, but any Civ that has a unique unit or building that can be purchased with faith results in all players being able to purchase that unit with faith. A good example is the Dene's Sacred Drummer.
I'm wondering if anyone knows how to tweak the files to avoid this. I've put together a MPMPM modpack that includes a large number of North and South American civs and many of those have these faith purchase characteristics. I did this for my on enjoyment so multiplayer is not a big issue for me. I can self-police and only select the purchases that I know I'm entitled to. I haven't noticed the AI civs selecting an opponent's units or buildings but I'd feel better knowing they were only available to the intended civs. Other than that, play has (so far) seemed go as it should. I do get an occasional CTD when exiting but the saved games have always loaded when I go back in.
