I think what he's really asking for is how to limit the user's TOTAL time
online for a (day|month|year) rather than just limiting the length of
each session.
For example, I have a BBS setup where users can only connect via dialup,
and are limited to one hour per day. Right now the time limit is
enforced by giving them a special Unix shell that keeps track of the total
minutes used today, and disconnects them when the total reaches 60 minutes.
The answer to the question is 'Livingston Radius cannot do this right now'.
I've started hacking on it to add the capability, but haven't gone very
far with it- enforcing time limits is really beyond what the Livingston
implementation is designed to do, but the actual code and testing to do it
should only be a couple day's work...
Now if I can only find a couple days to work on it...
