That is possible; doing so would create a new and different set of operational issues and implementation issues. It isn't immediately obvious to me that the alternative set of issues would be simpler/cheaper/easier than the issues Fernando's proposal raises. Another more fundamental question is how much operational risk the folks who deploy edge networks believe they have, and how much operational risk those folks are comfortable with. Some or many such operational folks might find all of these concepts to have excessive capital and operational expense for the perceived risk reduction. They might conclude that the "cure" is worse than the "disease".
