NAS is nearly analogous to RADIUS client. basically, it depends on the
thing that is talking to Freeradius to say how to configure kicking
someone off in real time.

You could stick a script before authentication happens to check
whether or not a user has exceeded his bandwidth and then either allow
or dont allow them to log on again but that seems like a bad way of
doing it.
