Preparing for my talk I was on the Symfony wiki and came across this:

This plugin allows you to add a simple Content Management System (CMS) to your symfony application with the following features:

* Uses Javascript and Ajax to provide a neat user experience
* Edit zones in pages
* Edit page URL (you can use / in page path)
* Edit content in the real context (‘edit in place’)
* Preview result
* Create and manage a tree structure for pages
* i18n ready (the interface is translated)
* l10n ready (a page can have different versions)
* support multiple templates
* Basic publication workflow
* Breadcrumb navigation
* User management is controlled through sfGuardPlugin

It is not aimed at replacing full-featured CMS packages, but offers a lightweight alternative for when you build a website that has to contain pages often updated by special users. It is voluntarily simple, and very easy to configure; so it should fulfill most basic CMS requirements.

Sounds exactly what we’ve been looking for (or at least intending to build)
