want 2 diff looking frontends pointing to backend

[tekmiester]

what is the best way to have 2 different looking sites that actually use the same instance of vbulletin?

I am looking to partner with another site and give their users access to my board but with the look and feel of their site. Hopefully it will give me the scale I need to get the board going.

So ultimately, it would be this:

Different banner
Different nav (their website nav with a subnav for vbulletin controls)
Different URL (for instance, http://forums.xyz.com redirecting to my servers)
Different theme

Same forums
Same DB

thanks.
