Started poking around with the wikimedia API. Have yet to figure out how to get it to return results based on the title of the page. (i.e. I can specify a user and get only that user's actions, but when I similarly specify a page expecting to get only the changes to that page, I get changes made to any page).
To start have been using the handy web-based form at http://en.wikibooks.org/wiki/Special:ApiSandbox
