Aaron Schulz picked up work on this project, and completed most of it. Testing is scheduled to happen by early August.

Aaron Schulz completed most of the features, and Tim Starling reviewed Aaron's code. Only a few minor fixes were required; the system should be deployed in early September, so it can be used for the deployment of MediaWiki 1.18 to Wikimedia sites.

This feature is now deployed on Wikimedia's sites, and we use it to do staged rollouts of new versions of MediaWiki to our wikis.
