As far as your setup goes, you may want to at least consider something like this:

http://advent.plackperl.org/2009/12/day-12-maps-multiple-apps-with-mount-and-urlmap.html

"The environment variables such as PATH_INFO and SCRIPT_NAME are automatically adjusted so it just works like when your application is mounted using Apache's mod_alias or CGI scripts. Your application framework should always use PATH_INFO to dispatch requests, and concatenate with SCRIPT_NAME to build links."

This should get you pretty much to the same place, but with the added advantage of being able to use Plack's debug panels etc. 

Hope this helps,

Olaf
