Hey, sorry about that, I should've thought of that.
But, I solved my Apache and FreeBSD 4.0 problem by adding the
following lines to the end of my httpd.conf file.

So, at this point, I believe that my theory was correct even
though I made an obvious error in my reasoning above.

Here's what I added.
#############################################################
NameVirtualHost 192.168.1.1

<VirtualHost 192.168.1.1>
</VirtualHost>

<VirtualHost 192.168.1.1>
  ServerName www.etiam.net
  DocumentRoot /data/web/www.etiam.net
</VirtualHost>

<VirtualHost 192.168.1.1>
  ServerName www.alluent.com
  DocumentRoot /data/web/www.alluent.com
</VirtualHost>

<VirtualHost 192.168.1.1>
  ServerName www.fineworks.com
  DocumentRoot /data/web/www.fineworks.com
</VirtualHost>

<VirtualHost 192.168.1.1>
  ServerName www.globalgastrohospital.com
  DocumentRoot /data/web/www.globalgastrohospital.com
</VirtualHost>

########################################################

I also had to add a line to my /etc/hosts file.
My hosts file now contains:

216.15.83.94    alpha.etiam.net alpha etiam.net
192.168.1.1     me.etiam.net

(Without the me.etiam.net thing Apache was trying to do a reverse
DNS on 192.168.1.1 or something that was making it take forever to
start up)
