I also think that administrative "link down" isn't useful for the case 
described above, but it might be useful in other cases.  For example, it 
may be a way to quiesce the link while not having to tell all upstream 
consumers to "go away" first (as you'd have to do when "temporarily" 
deleting a link).  Why an administrator would want to quiesce a link? 
I'm not sure.  Maybe Jim could provide some use cases for this.
