Re: Potentiometer + cloud + monopoly
It all needs to be autonomic and self-configuring, including secure enrollment of new devices. What it doesn't need (from the consumer's point of view) is to depend on proprietary or cartel solutions for that. That's the difference between your £8 spark plugs and £130 injectors (whose fair price is probably £30 at a guess). So beware of Big Blue (or Cisco, or anyone else) who offers the One True Solution for IoT security. The One True Solution includes a monopoly rent.
