Thanks to everyone for their advice. I'm running apache on different high ports
rather than use an additional IP address. Wether I use an IP address or a
high port, I still have to maintain N number of configurations for N number of
RT instances.

The configuration now looks like:

    ProxyPass /demo       http://request.domain.com:8011/demo
    ProxyPass /systems    http://request.domain.com:8012/systems
    ProxyPass /facilities http://request.domain.com:8013/facilities
    ProxyPass /operations http://request.domain.com:8014/operations

(Yes, I'm still obfuscating our domain even though I was tired in the previous
email and leaked both the domain and the IP space used. How lame of me).

each of these apache configurations have a very typical instance of rt
configured:

<VirtualHost X.X.X.15>
    DocumentRoot /proj/request
    ServerName request.domain.com
        PerlModule Apache::DBI
        PerlFreshRestart On
        SetHandler perl-script
    <Directory />
        Order deny,allow
        Deny from all
        Allow from X.X.*,Y.Y.*,Z.Z.*
    </Directory>
    <Location /INSTANCE>
        PerlHandler RT::Mason
        PerlRequire /proj/request/INSTANCE/bin/webmux.pl
        AuthName "Request System Authentication"
        AuthType Basic
        PerlSetVar myPDC PDC
        PerlSetVar myBDC BDC
        PerlSetVar myDOMAIN DOMAIN
        PerlAuthenHandler Apache::AuthenSmb
        require valid-user
    </Location>
</VirtualHost>

I've modified my apache startup to look for /var/apache.* (I may investigate
something more elegant), and start up an apache process for each apache dir if
the httpd.config exists in /var/HTTPDIR/conf/httpd.conf

Onward to future rt battles...
