Or, one could make sure everything has a globally unique IP address and is
using reasonably secured communications. The downside is that one
then can't defend the existence  of those empire-building middleboxes. It
is not the telco way, so is of course unthinkable. Like anything beyond
WAP was on cell phones a decade ago.
