Theory
The idea behind Internet 0 is to provide a general-purpose physical layer that operates well in many media. As such, it is very similar to morse code: a general-purpose layer 1 for the Internet. Logically, this is a recursive application of the internet principle (a ubiquitous protocol) to layer 1 of the network. The pulse-position modulation of Internet 0 operates best over a segregated wire, but it works in many media. It has been tested over radio frequency (RF), infrared (IR), ultrasonics, optical, DC and AC power wiring, and even physical representations such as printed bar codes and engraving on a key.
One of the main advantages of this approach is that routers become very simple. They are just a sensor, pulse reshaper and a transmitter.
Coupling the reusable physical layer to the internet protocols enables a network with very inexpensive nodes that is also addressable from the global Internet.
