View revisions by node ownership

I have an idea for a feature which would make this very usable for me (and set it apart from the previously mentioned Diff commit).

It would be nice if you could say, "View revisions of OWN " and "View revisions of ANY ". Sort of like "Edit own Page, Delete own Page, Edit any Page, Delete any Page", etc.

Here is a practical example: I have a Content Profile installed, so each user can create a profile node for themselves. I would like them to be able to use revisions, and see/revert their own revisions-- but not be able to see anyone else's profile revisions. And obviously, the administrator should be able to see and revert anyone's.

What do you think?
