The Not-So-Smart Grid

The "Smart Grid" is the future for the power companies, where the electrical grid can be monitored with the promise of better service, more effective billing, and so on. However:

A hacker wearing a fake beard and dark sunglasses took the stage at a computer security conference in Miami on Thursday and showed a group of about 60 security researchers how to intercept the radio communications between Silver Spring Networks, a maker of smart grid technology, and its clients, which include major utilities like Pacific Gas and Electric and Pepco Holdings.
Gee, a computer network that we understood (or assumed) to be secure that maybe isn't? Why, I'm shocked. Shocked, I say!
