The issue is that the server needs to know the hostname given to the 
browser to find the matching certificate, and the only way to do that 
and stay on the standard port 443 with the apache version on centos is 
to bind each virtual host to a different IP address.  Per the apache ssl 
faq at http://httpd.apache.org/docs/2.2/ssl/ssl_faq.html#vhosts2, 2.2.12 
or later supports SNI where the browser passes the hostname before the 
ssl session starts.
