I am jsut wondering whether trhere is a way of mapping elemenst only for certain groups of users.
For example, there may be areas that may only be passed by certain groups who are allowed there by their job or something.
It would be good to have a way of sort of "categorizing" map objects, for example there could be a field "limited_to" that the ncould contain something like "oxford_students".
When downloading maps, these areas could be enabled or disabled in some way.
Any ideas about that?
