I have created a special page for MediaWiki that allows you to watch
activity on your wiki in real-time using AJAX. You can preview it at
http://wiki.case.edu/Special:AJAXWatcher
It is still a work in progress, but an extension like this goes a long
way towards making MediaWiki a better product for real-time
collaboration. I haven't excessively tested it across browsers, but it
works in Firefox 1.5 under Linux.
The source code can be obtained at

As always, I am open to any suggestions or observations you may have.
