I ended up adding all users that needed an internet connection by hand 
at request.
Maybe you could change the PHP scripts of the user manager to have a 
dropdown-list with all users that fetches them from an external database 
(MySQL or somewhat) so that you can add users very fast without having 
to type everything in by hand. Maybe I will change the captive portal to 
not delete expired users but to flag them as expired, but I determine 
when that will be.
