You can write your own module or program that will check you limit and if
user is over call radclient and send PoD to your NAS. You are sure that
your NAS knows what to do with PoD?

No, because it's a very bad way of doing things.

There are far better (tried and tested) ways of enforcing limits using
counters/sqlcounters at login time. If you use them, your user will not be
able to go over the limit, as NAS will disconnect him (without any need
for external PoD) when the limit is reached. And you don't need interim
accounting packets.
