The idea is simple. Everone interested, downloads a worldspace map (.esm master) and a blank .esp. They then open these in the CK and lay claim to 1 cell (x,y) in the map plus an additional secondary cell (x,y).
This would be based on a first come, first served basis. If your claim has already been take by someone else, you'll receive an email telling you to use your secondary x,y cell, or if that's not available, to pick another.
Once you recieve confirmation, you can start work on your own home, exterior and interior. Of course, it doesnt have to be a house, it could be a mine, a cave, a dungeon,...anything you want.
Two things that must be present are
1. An avatar representing yourself. To this you can add your own dialog, armour, and possibly your own quest.
2. A message must be created with your name, and attached to the entrance / entrances of your mod.
Other Info
The plan so far is to include 4, 5 or possibly 6 cities. These too, would be partly claimed (not a whole cell) and your chosen town/city dwelling/shop/blacksmith/mansion area would be given to you. This would probably result in having to duplicate your avatar so that the player meets you in the cities and out in the wilds. You would be neighbours with other folk who want to participate.
It could even be possible for some folk to get together and collectively create small hamlets,...if they so choose.
The possibilities are endless, just use your imagination.
Of course every persons avatar would be marked as essential, so you wouldn't be killed off.
The thing i think that would be really funny, is picking other peoples locks and 'exploring' their property. Again, you could set numerous deadly traps inside to prevent the player from doing this.
Obviously, there would have to be some guidelines put in place. It's just a storybook at the moment, but depending on the interest, it might make it to the production table.
Another point, this isn't going to be a short term project. I think we're looking at a year minimum, so there would be no hurry to get thing done, or abandon your current project for the time being. All getting done at a leisurely pace.
What are your thoughts on all of this ?

Here's some screenshots taken in the CK, of the Worldspace -

This is the bare worldspace, with the base textures put down. The area you see with the little yellow squares is a 15x15 cell area, just to give you a rough idea of the size. The main mountain ridges you see, define the border of the worldspace, although this could be changed, to use the area to the South West, if needed.
It looks a lot better ingame,...trust me.
