If you are really serious about using 1 SSL certificate for all your 
connections, you need to understand SSL much better than it appears you do at 
the moment.  Some things to note:
1) The Common Name of the SSL *must* match the name the user gives in the 
hostname portion of the URL he enters in his browser, or else the browser will 
complain.  It doesn't matter if the name is provided as an IP address or a 
normal string name.
2) The direness of the complaint is totally dependent on the browser and the 
version of said browser.
3) To have one certificate match multiple hostnames, you need a wildcard 
certificate, where the common name is like "*.domain.name".  Do tons of 
research before attempting.
4) Internet Explorer interprets wildcard names differently than other browsers, 
and the spec as far as I can tell.  Where host.domain.name will match the 
above, host.sub.domain.name will not.  IE is the only browser I've found that 
imposes this limitation. And I don't think you can do "*.*.domain.name" to get 
around it either.  Try posting to an SSL group to find someone more 
knowledgeable.

If I wanted to use the same SSL certificate for all virtual hosts
does it follow that
