I agree middleboxes aren't desirable. On the other hand, I doubt very
many people will applaud a clean architecture if that means they have to
upgrade large numbers of individual hosts rather than a few middleboxes.
And it's not just deployment; implementing policies on individual hosts
is much harder than doing it on middleboxes or border routers.
