I'll probably go for the unique IP if it's available, but I'm curious  
as to how the senario is possible without a unique IP. Looking at http://httpd.apache.org/docs/2.0/ssl/ssl_faq.html#vhosts2 
  (right at the end) it seems to say that SSL hosts on the same IP can  
be differentiated using port numbers:

- So could I then use mydomain.com:9876 or similar for https?

- If so, then why couldn't I then use a certificate for mydomain.com: 
9876, to avoid warnings?
