Comment (by dd32):

 Ultimately, If the IP address of current site is redirected elsewhere,
 it's not going to end well..

 The "common" way to do that would be have the other server named
 differently eg:
 {{{
 ServerName mysite.com
 ProxyPass /special http://www2.mysite.com/special
 }}}
 that way DNS hacking isn't needed.

 The Proxy support in core is designed for outgoing requests, rather than
 loopback requests.

 In your case, I'd be filtering outgoing HTTP requests, If it's for the
 current domain, alter the request to goto http://127.0.0.1/ and force a
 Host header.. [http://wordpress.org/extend/plugins/wordpress-beta-tester/
 WordPress Beta Tester] plugin intercepts connections and rewrites them,
 you might be able to do something similar.
