The front server just needs to run apache and the mod # rewrite stuff to generate a page back which is a redirect to the real # site for those pages. But that isn't efficient in the slightest. From a simple request->response, you've created a request->redirect->request->response chain. Add the possibility of the redirect being to a different host and you can add a slow DNS lookup in the middle of the chain. And if you do this all transparent to your page authors, then add the potential for a graphic ladden page to be getting redirects for everything it loads.
I've seen crap like this in action and its scary. Modperl+apache != efficient load balancing.
Now, if you could actually hand off the network connection to another box, without having to send any client-bound messages, that would be cool.
Hmm.... G'day!
