Setup SNI/SSL in cPanel

Question

I am looking to setup SNI under cPanel, and while I know it's not directly supported just yet:
http://forums.cpanel.net/f145/case-46856-sni-server-name-indicator-ssl-support-cpanel-83661.html

That doesn't mean it can't be done as far as I'm aware.

Does anyone know a guide or have any advice as where to look to set it up?

Any help would be greatly appreciated.

-------- UPDATE --------

I found this link which details how to set it up on Apache but have been told that cPanel overrides the config files:

Answer 1

WHM 11.38 now supports SNI:

Server Name Indicator (SNI)

Currently, it’s common for each SSL Certificate to require its own dedicated IP address. The cost of this address is typically being passed down to the end user.

SNI is able to change this paradigm by indicating what hostname the client is connecting to at the start of the handshake process. This allows a server to have multiple certificates all installed on the same IP address. Users on shared servers, that support SNI, will be able to install their own certificates and bypass the need for a dedicated address. While this saves on the cost of the dedicated IP address, this also helps reduce the need for extra addresses.

In order to experience the full benefit of SNI in cPanel & WHM 11.38, an operating system that supports this functionality will be needed as well. CentOS 6 is a prime example of such an operating system.

This is the closest I've seen, using mod_gnutls. http://blog.dembowski.net/2011/10/28/sni-on-centos-5-6-mod_gnutls/

Apparently installing an updated OpenSSL can break lots of other tools and if you install a separate copy you still have to compile Apache to use that one, which breaks the autoupdater.
