One IP SSL web servers.

RFC3546 introduces an extension to TLS that allows SSL-enabled name-based vhosts on a web-server. Essentially it eliminates the current requirement that every site name has its own IP address - making vhost configuration for secure sites somewhat less fraught than they are at present. The forthcoming OpenSSL 0.99 is purported to support it. mod_gnutls for Apache currently does (experimentally).

I propose it should be a target that Ubuntu supports this feature in the upcoming LTS release.
