GE has been shipping appliances for the past three years that are “smart.” Smart meaning that they are equipped with ZigBee wireless capabilities so that your appliances can communicate with each other—and more ominously, with your utility company or anyone over the Internet. Most of the ZigBee capable appliances aren’t even labeled as such.
This is potentially a huge privacy breech. It seems that few of these appliances communicate back… yet.
