Right on, Terrell.  This is how I have done it for labs and for the
PTC email garden.  I am thinking that /etc/hosts.allow needs to be
modified, and I think I had to assign somewhat different hostnames for
the range in /etc/hosts.

This is a key point for many.  Often times the congestion on your
server is not at your dual or core or octa CPU or in your RAM or in
your disk I/O.  It is at your single NIC, even if it's a giganic,
trying to serve all that data.  I rarely do an install with only one
NIC for the LAN.
