Agreed. A guarentee that the process listening on a particular port is
what you're expecting isn't something that upstream can give. It needs
to be done through some situation-specific mechanism. There are a
number of options here, of course: SSL, Kerberos, SELinux, even things
like the tiger IDS. Reserved ports really aren't all that great a
solution in the end anyway, to be honest.
Enjoy,
