As far as I know there is also the possibility to use a different port for the second vhost.
But in this case you will always have to type the port in your address field (e.g.

No, it isn't. If you wish to support IE 6 or 7, chrome or safari on
windows XP - which is a huge, enormous section of the browser
population - then you cannot use SNI. Trying to say otherwise just
because YOU only use firefox is what is misleading.

More to the point, show me one major commercial deployment actually using SNI.

The OP also indicated that he had already purchased his certificates,
thus precluding wildcard domains. It is much cheaper (by far!) to get
an additional IP than it is to purchase a new wildcard certificate.

So, yes, very clever to note SNI, however it is not a reliable
solution for ~40% of users on the internet.
