  Perl modules exist to do 99% of that work.

  No, we need a RADIUS server that does DHCP, too.  I don't think it's
that hard, especially with the recent 2-octet "type" support for

  i.e. ISC DHCPd is huge, complex, and doesn't support leases in a DB.
FreeRADIUS already has a multi-threaded UDP server core with a generic
policy engine, that back-ends to multiple DB's.  The CVS head already
has sql_ippool.

  It's not hard... really.
