I would like to use MediaWiki as the back-end content management system for a corporate site, and have a simple page-renderer of some sort which would handle the front-end. Basically this would be a stripped-down fork of MW which would not have editing or user account features but would simply serve the content. I know I can do this by configuring a standard copy of MW to disallow editing and such, but I think that a stand-alone product would be much faster and more secure and efficient.

In the setup I envision, www.example.com would serve the content, and edit.example.com would serve the standard MW interface. The "edit" subdomain would only be visible to people inside my corporate network.
