Ok, but this is also rather static and only changes if a new number is 
subscribed to the system, isn't it?

What I'm looking for is a solution to maintain a very dynamic location 
database in enum.
I've a few thousand subscribers registering from IP addresses that are 
assigned by DHCP, so they can and do change from one register to the next.

So I want to perform something like:

if(www_authorize("my.domain", "subscriber")) {
   save("location"); # just for backup
   exec_msg('/foo/nsupdate_wrapper register');
}
else { ... }

nsupdate_wrapper calls the nsupdate-utility and dynamically updates the 
DNS entry.

The only problem I can see is how to remove expired entries from the 
enum tree.

Does that make sense?
