I know for a fact that the approach works:  requests for the virtual
domain can still acquire the tools from the "hidden" CMFSite.  In our
case, rather than VHM, we use a pair of access rules, which decide
whether to activate based on the presence of the 'Via:' header (set by
Squid for the "retail" view). 

The first access rule is an ExternalMethod root of the ZMI, with
source::

    def redirect( self ):

        """ Move all requests over to /CMS/site
        """
        request = self.REQUEST
        header = request.get( 'HTTP_VIA' ) # Set by Squid

        if header: # Served from the squid cache tier
            request[ 'TraversalRequestNameStack' ].extend(
                                       ( 'site', 'CMS' ) )

The second access rule is another EM, in the 'site' folder::

    def rewrite( self ):

        """ Make the current folder the virtual root.
        """
        request = self.REQUEST
        header = request.get( 'HTTP_VIA' ) # Set by Squid

        if header: # Served from the squid cache tier
            request.setVirtualRoot( [] )

Obviously, this will need tweaking if you aren't serving the virtual
domain behind Squid ;).
