You'd need to use a subdomain to identify each part of your site, and you'd need to use an htaccess file for the routing. It can be done, not idea how though. htaccess is currently beating me by 2 to nil, so I need to even out the score or better yet, tip the scales in my direction.
If you can sort out the subdomains, I might be able to help with the htaccess file (although I can't promise).
