Listening to this guy talking about a 'sledgehammer' approach to emergency response radio/cellular networking, I'm struck by how cool it would be if those incredible communications devices (smart phones) most of us have in our pockets... could be untethered from their cell towers & so they could communicate directly with one another... they have the inherent capability, but then the telcos no longer control the interactions (& can't charge for them)... I think we need more forceful regulation.
