The ABC is reporting the development of an emergency broadcast system that will allow the government to remotely turn you radio on and inform you about an impending disaster. The Yellowbird alert system is being developed here in Canberra by Advanced Alert. So it must be a pretty powerful remote.
I think its a great idea and can see a lot of benefits from this idea, especially when the zombie hordes descend, but the paranoid cynic in me thinks of all the political uses it could be put to. Douple plus good style.
