prevent multiple simultaneous page editors

The big problem is working out when someone’s buggered off mid-edit, leaving your page locked - and some automatic, periodic mechanism to reset that flag so the page can be edited again.

With the "DokuWiki approach" you wouldn't need a cron script to check your locks table. You would simply need to check two conditions to know if some piece of content is locked: "Is the content_id in the locks tables?" AND "Was its timestamp generated less than 15 minutes ago?"

What you should decide is whether this basic collaborative editing management meets your project requirements.
