file-based CMS

For some time, I've been developing a GPL'd, file-based, XML-capable, CMS, with a GUI content editor, that does not depend on any database, although certain modules may, like a bookmarker module. I'm about ready to release the first beta to the public. It is intended to share some principles of wikiwiki, but it will eventually be much more than a wiki, actually a wiki would be just one module. It is also intended to be like other CMS systems such as Post-Nuke that allow for plugable functional modules. In fact, a main goal is to provide unlimited plugin capability with other independently developed projects. I am not sure if this is realistic, since I haven't attempted writing any integration code yet, but I'm interested in including Gallery, Bookmarker, FUDForums, PHPDocumentor, PHPOpenTracker and other functional modules. It is by no means complete in terms of the number of features that I want to develop, yet it does have a great many features. I do not want to continue to develop this alone, so I am looking for other people interested in a file-based CMS. I'm wondering if anyone on this list is familiar with any other good file-based CMS systems. I could only find http://www.php-update.co.uk/. I'm also interested to hear your experience with CMS in general. Am I doomed to try integration with 3rd party modules? Am I doomed to try a file-based, XML content approach? I'm interested in releasing (with a PHP-compatible license) any of my code that might be suitable to PEAR, so I hope that some of you will get to know me.
