how about updating the NAS list from SQL via, for example, an SNMP write command
or a special RADIUS command packet. both of these could have security protection
to prevent DoS (eg the SNMP write from only certain locations (firewalled) and
has password too of course... the RADIUS command packet could have a shared
secret requirement and/or use the FR unlang/attribute protections for access/accept
