You write your own which interfaces with one of the supported backends,
ldap, sql, redis, flatfiles etc.

mysql

Yes. Use the radcheck/radreply tables from the schema that ships with the server.

radacct

yes. But it's deployment specific. Generally you perform the check when
receiving an Accounting-Request and do something when the use is overlimit.

The something might be sending a disconnect-request to the NAS.

You can do either. If you use pools on the server the IP address is returned
in the Framed-IP-Address attribute.

That's outside the scope of this mailing list.
