    I've seen things like this done before.  Heres what I know:
If you want to run 2 different sites, with different 'hostnames', and have
each base URL (such as http://www.nbcc.org.au) go to a different URL, the
way I've seen it done is as follows.  You give the machine two IP's, and
set up the DNS for www.nbcc.org.au to point to one, and the www.nswcc.org
to point to the other IP.  The HTTPD has configuration files that let you
tell it which IP's should point to which pages.  My experience has been
with Apache, so I don't know how/if CERN does this.  Apache does this
pretty well.  
    Only one HTTPD runs, and it sorts out from the incoming connection
which page it should go to.  Apache's web page tells all about it:
http://www.apache.org/docs/virtual-host.html.  Again, my experience has
been with apache, so I'm not all that sure about CERN.  Just wanted to
drop my 2 cents.  Good luck!
