My son, roomate and I have installed the Visa 3.10 mod into our civ game. After playing it for a while we decided to make a hot seat game. This is the process we have undertaken and it is repeatable. I make a map in a single player game, using Fractal, Rocky, and Huge. I then use the world editor to make the map a little more interesting, adding in some island chains and other terrain to make the game more fun. After we do this, I save the map, and start it in hotseat. Once the new game begins, all newly created cities are instantly given the jewish religion, and it continues to instantly spread to all cities. We are playing a game now to see what happens when someone researches Monotheism.
