ASP Plugin/Template Driven Portal Project

I'm currently in the middle of the most advanced ASP project I have ever worked on, and was wondering if I can get any feedback on what anyone thinks about it so far (or suggestions for improvement later, etc.)

Basically, it will be a single core set of ASP files, that will allow anyone to set up a webpage in minutes by simply selecting a pre-developed site template, and pre-developed site plugins (a plug-in being anything from a menu, to a CC processing tool, etc.), so that user's can simply "manage" their site look/use rather than program everything over and over again. In the end there will even be an import to instantly convert any existing site.

Developers can build templates and plug-ins at will, and will be interchangeable on the site with the click of a link or button.

This project is planned to be open source but is still months away from completion, but to check out a sample of how it basically will work, we are currently testing it at URL.
