Just like with the Vin# burned into every car(and now on many of the parts as well) sold in the US to help track car thieves, we need a system where every device capable of communicating must have a serial number that is burned into the chip and that must communicate that number before access can be given to transfer data.
And every communications capable device being sold would match its serial number or numbers with the name and address of the person buying the device. In effect you would have a national registry matching a person with the devices they own and it could track everytime that device links to a provider network.
Of course, there would be hot, stolen devices - just like there is with cars and guns. But 95% of the devices would be able to be traced back to a specific person. Of course, all the people who think they have a right to privacy will whine, but I never hear them whining about how their car can be tracked back to them.
No offense, but how the hell would you keep a registry of all the people? What would stop me from buying a wifi card online from an overseas retailer? The list goes on.
