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.

• 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 Manchester code. (The soundmodem software package is more or less what we want)

: We can probably only control the frequency and duration of the sound from software, is this what we want? : How do we analyse the sound from the microphone?
