The freenix one was pretty dead stupid/simple.   It just set the
protocol to 0x0666.  To my knowledge, no one outside of us has every
really used the freenix console, although I did get a few requests for
the code over the years.

Nope.

Nope - I believe the paper makes the argument that you could use VLANs
to enforce security, but our primary use for the ethernet-based
console was purely pragmatic -- the hardware we had didn't have
serial, video, or any other means of getting output.
