Correct me if I'm wrong Bruce (or anyone), but here's how I see it
(below, inline)...

But as soon as you do that, the site will stop working.  If it takes a
total of an hour to do 250 sites on your RaQ, then the first site will
be down at least an hour, the second a bit less, etc.

Are you saying an ifcfg-eth0:x file (for example ifcfg-eth0:9) can have
more than one IP#?  It looks to me like you're saying that, but I don't
believe that's possible; my understanding is you'd need to create new
ifcfg-eth0:x files, which is what I've always done.

But either way, I don't see how the site will still resolve at two
IP#s... the issue, to me, is in the httpd.conf file.  It points input at
only one IP# toward the name-based container for a particular site.

On that we agree <smile>.
