I’ve been playing around with this idea for the past couple of months now. It might get code if and when I have the time. It’s a CMS model that’s easy on database CPU load and bandwidth usage (if you’re running a DB server that is not your webserver) and caches parsed content to html files that are generated using dynamically created, locally saved XML content files and XSL stylesheets. In this model the forntend has an AJAX interface with widgets and toys that should feel right at home because of how the backend handles data and communication. The result should be a mighty fast CMS system with some awesome expandability possibilities.
