Alright. Here is my model. If someone creates an area using the permission "protection add" they should be the owner of the area by default. By making the "Protector" the owner of the area that he/she created, using the permissions "delown,listown etc." can only manipulate his own area. The Protector cannot remove or manipulate someone else's area if he doesn't have non-own permissions "del,list etc." .
The non-own permissions "del,list etc." should be set automatically for the admin/operator, and "delown,listown etc." permissions for specific group that someone wishes to create (VIP, donators, etc).
