From my understanding, then its a matter of coding. They would have to make different codes for each new privat server, and that would be a lot of work.
I do not belive that it is going to happen. They would have to re-mesh most of the continent (unless they have backup of their mesh pre-cata) + redo alot of the code I'd belive.
You'd also need new or re-written routines for each class and so on.
