If someone has a chance, it would be cool to put those options into nnrpd
-D as well.

Although another good solution to this is to run nnrpd under some
inetd-style server that can do rate limiting or limit the number of
connections per IP address.  tcpserver unfortunately can't do that; does
anyone know if xinetd can?
