====== Ethernet over tin can phones ======

The goal of this project is to get a data transfer going, over a tin can phone, and ultimately play Quake over a tin can phone. Because we can. Hopefully.

===== Plan of attack =====
  * Use a TUN/TAP device, probably controlled from Python.
  * Use two tin can phones in a unidirectional manner to avoid half-duplex.
  * Use a speaker and microphone at each end.
  * Encode packets in sound, maybe something [[wp>Manchester code]]. (The soundmodem software package is more or less what we want)
FIXME: We can probably only control the frequency and duration of the sound from software, is this what we want?
FIXME: How do we analyse the sound from the microphone?
