With that amount of revisions to handle, I can easily see your reasoning behind it. It's called sanity! lol
If you'd like another beta tester, I'd be willing. Anything that simplifies the revisions task is a friend of mine. Plus, I like the simplicity of what you've shown me, just like this plugin it looks very well put together, regardless of the auto function...even though that would make it a totally awesome plugin!
I'm not the brightest regarding WP along with the many plugins, I'm still relatively new here and finding out what works and what doesn't, do you know of any reliable recommendation lists of plugins for the multisite environment? It's just that it sounds like what you are handling is something I am attempting to tackle, and it would be very helpful to learn from others with greater experience than myself on the "tips and tricks" to better manage something on that order.
