That's a good idea but I wonder if anyone would buy them? Obviously the technology inside of it would be a quantum leap for any tech company that could get their hands on it. AT&t or ma Bell or Motorola would all easily fall over themselves to hand you several million dollars for it just so that they could have their top researchers reverse analyze the equipment.
The downside to that issue though is that it would be very difficult to get in contact with the right people to sell these devices at the right price.
