As long as the previewing of edits requires a server query, previews should also check if the proposed edit would produce an edit conflict, and return a notification to be displayed to the user in the rendered preview screen. This should apply for the Show Changes function as well.
Mmm, this could indeed be a nice plus. Would probably want to do a merge test, and only throw up the warning if there is an issue -- at which point one could click for further details. (No sense cluttering up the view with a giant conflict screen while you're still working.)
