Who is this "user" you speak of? :-) I'd extend that a bit for batch systems: invoke some kind of tool to file a trouble ticket to get the operations/support group's attention, as there won't be somebody sitting at a console to watch. Alternately, you could view this as generating a big red screen, just realize that any users are sitting "someplace else". Yeah, some of us still have batch operations going, as well as a web app or two.
