What do Sayada, Tunisia, and Red Hook, Brooklyn, have in common? At first glance, not much. One is a fishing town on the Mediterranean Sea. The other is a waterfront neighborhood in an industrial section of America’s largest city. But both are using a networking technology that is cheap, relatively easy to set up, and remarkably resilient and secure.
