That only works if you have only one address on the machine and.

Actually it works fine on machines with multiple IP addresses for both 
FreeBSD and CentOS.  And IPv6 enabled servers can easily have multiple 
IPv6 addresses.

What Owen meant was that if you expect it to answer *only* for a.b.c.d:80,
and *not* to answer for other addresses/interfaces, you may be in for a
surprise (consider a DMZ host where you have:

outside world -  128.257.12.2
inside facing - 192.168.149.149

VirtualHost 198.168.149.149:80 # super-sekrit corporate internal site

Changing that VirtualHost to *:80 will probably cause some grief. ;)
