Seconded. See my earlier reply to saberworks post. I've started using it in a real-world application and it works quite nicely. I have a couple patches into the author for some enhancements I needed, who seems willing to put them in. :-) If you're interested the patches include:

• Passing in the pre-translated application name to the application. Useful if you want to programatically create links between applications.
• Under CGI mode, pass-along any params set via new() in the instance script.

It makes it very easy to setup multiple applications w/o having to add <Location> (mod_perl) or instance scripts (CGI) for each one.
