approve member video edits

i want to keep my members to be able to edit there own video description, tags, channels etc but it would be good to have some control over it.

For example i check every video uploaded and fix any bad descriptions, wrong channels etc but allowing the members to edit the video lets them re-add them to wrong channels and spam there site constantly in the description and add 100's of wrong keywords to get there video shown.

for this reason it would be good if video edit's were submited to admin for approval before going live, or at least some notification to us that a user has edited there video so that we can check it to see its ok.
