What does OCC setting do?

A quick search of the forums didn't uncover existing thread on this subject, so I start one.

What does the one-city challenge (OCC) game setting function in terms of changing the application behavior?

I know how the in-game experience changes, I have played couple OCC games. I am looking for a modder's or developer's point of view, so pertinent questions are:
Is the behavior hard coded deep in the core somewhere?
How is the setting stored in the game, is it accessible?
Can you change the behavior?
What do you have to take into account when designing a mod with OCC games in mind?

My angle to this is that I would want to modify the OCC concept a bit. I like concentrating on a single city, but I get frustrated when I don't have any ability to reach out (usually, for a resource). I know this sort of is the point of the concept, but it would be my mod, so I can do whatever pleases me. :-) Being as I am, a generally lazy person not really looking for doing any detective work myself, it would be real nice if someone had already figured out OCC.

The specific thing I am looking to implement is a colony a la Civ3. This would be a possible mod for games other than OCC, and I would implement it with reusability in mind, but first and foremost it must work in OCC. I can quickly think of two different ways to start, each with its own pros and cons. Most obvious way would be a new worker action creating a terrain improvement: colony (plus some scripting). The other way would be to make colony sort of a mini-city (plus some scripting). Worker action route would probably be easier to implement, but it doesn't have the open possibilities of a mini-city.

(I'm assuming a lot here, as I actually don't know much about the limits of Civ4-modding, for example, if it is possible/easy to make new worker actions. On the positive side, I do speak fluent Python+XML. :-))
 
At the very least, if you choose to play an OCC-game, you shouldn't have to build (minimum) 4 theaters to get to build shakespeare's... of course, that is impossible and should change when you check the OCC-box.

Any way to change this?
