Calling to GM's out there. Collaborative world? Any takers?

[Tobaris]

I have been planning to make several of my games connected in an ongoing gameworld that will have lasting repercussions and will grow and change as time goes on. However as PbP can make even the shortest adventures several months long, I'm looking to collaborate. I am interested in working with some GM's to make this idea grow. I will also threw this post up in Recruitment as well, but I'm hoping to recruit some interested takers.
I am interested in running areas with and without AP's.
So far I only have one game I plan on officially making a part of this world. That's Empire, Kingdom or, History? Although I may add Rise of Thassilon.

I think there are several options with this idea.

Option 1:

Each interested GM takes responsibility for a region, adventures that significantly cross regions should be run by those who are responsible for them. Although one that skirts a region isn't as big a deal.
Further on that idea, those GM's can then let me know the rough direction they want to take the region in and I can work with them.

Option 2:

We establish GM responsibility by campaign. Thus a Jade Regent Campaign would be the responsibility of one GM and a Skulls and Shackles would be the responsibility of another. If you are planning a homemade campaign then you could let me know where your campaign will take place and what it will cover so we can work around overlap.

If you can think of other options that might work I would love to hear them.

One important point about this idea is that the world will progress in it's own timeline which will change compared to the official setting timeline. Also this would mean that an official campaign or adventure could only be run once in world. Any results from an adventure or campaign will affect the rest of the world realistically and continuously.
Any ideas or interested GM's?
