Recent changes view with RSS feed

Is it possible to create a view that just shows the most recent changes to your site, including new content, updated content (if updated, showing a link to the diff of the latest revision)? And an associated feed for it (where each feed entry is a single change with the full diff included).

Yes this is exactly the functionality the http://drupal.org/project/recent_changes module provides. However this is essentially unmaintained. There has been a single dev release for 6.x a year ago. The RSS feed doesn't work at all in 6. And 5 has had a security hole where non privileged users have been able to access pages they shouldn't via the RSS feed.

I'm not a developer, but have offered help testing out any patches in the recent changes module but there's virtually no activity over there.

Ideally Views would be able to create a view like this anyway. I have tried, but get stuck with trying to show a diff of revisions for the change.

Is it possible?
