If cakePHP works for you then use that. I'd look to build something that uses something that PHP and cakePHP is good at. For a while I've been thinking about a wikipedia for apps. Where people contribute code rather than text and help others build applications out of it, by using a plug-n-play sort of functionality. From the 10 minutes I spent thinking about PHP, it seems to me that the one thing it has going to it is that it makes it easy for your users to upload code onto the site to modify it. E.g. Ning and Jotspot. So maybe instead of a cpan for cakephp. A cpan for web apps. Where I can go to create a basic application, by choosing modules and plugging then together or adding applications that others have built to my stack.
