From the website:

MySource Matrix is a powerful Open Source Content Management System (CMS) written in PHP and is suitable for many types of organisations.

MySource Matrix is intended for use by mid-sized and large organisations rather than for use for smaller systems (i.e. less than 100 pages). The real benefits of MySource Matrix are appreciated by organisations who are looking for a publishing solution that includes:

* A completely functional GUI cross-browser interface that does not require high-level IT skills to operate (no programming skills are needed to use any of the features of MySource Matrix)
* Rich content editing for users with little or no IT skills
* Comprehensive content versioning and audit trails
* Industry leading standards and web accessibility support
* Definable workflow
* Granular Permissions
* Content locking (check-out) to ensure editors can work collaboratively
* Flexible and enforceable metadata schema
* Link management (ie cannot delete items and cause broken links in a site)
* Functionality to separate design from content for improved maintenance and ability to present content to different channels such as text-only or Blackberry.
* Dynamic content personalisation and other portal style functions
* Internationalisation support
* Easily extensible architecture with plug-in modules such as calendars, discussion forums, search engine etc

Could be interesting, but the problem with commercial solutions is the lack of a volunteer developer/support community.
