Outsmarting the smart meter
Interesting idea of transparent proxying and sending back bogus readings to the energy company once you get past the fact they are pushing their honeypot/traffic monitoring device. Going to be much more investigating of these devices as they get more popular.
Imagine a thief being able to sit outside your house, get in to your wifi and then in to the smart meter that tells him what goodies are connected. Could make a decision which house to burgle based on that :P
