A brief note, we're about to start a stress test of EtherEditor, an extension for real-time collaborative editing, at 20:00 UTC. If you'd like to help out, or if you'd like to watch, do please join us in #ethereditor on Freenode. If you don't have IRC for whatever reason, but still would like to help out with the project, feel free to email me (either on-list or off) or just check out the mediawiki.org page about the extension [0].
