Thanks Mr. Egan!

It's just a 1U Pengiun Computing Relion, running a few IP addresses
- yep, they will be from the same Class C range.
I'll only use 1 ethernet controller, although it has two.
I have a few domains to hit off of Apache (VirtualServer).
Nothing will be hanging off of the box (i.e. it's a dead-end, no need
to route anything).  Just need http/s and ssh.

Come to think of it, there's no reason to have SSH exposed to
more than one IP.

Perhaps another way to approach the question is: what other
method is worth considering for hosting a few web sites (different
domains, all standard port 80) off of one box?
