I've been working on something similar[1] for a few years. Don't forget that you can use tun/tap devices to avoid re-implementing TCP/IP, and to gain interoperability with OS services! [1] https://github.com/piannucci/blurt/tree/master/blurt_py_8021...
What throughput does your modem get?
Using vibrations instead of electrons to transmit data over a wire?
Do creatures like dolphins do this?
Slightly unrelated but curious; have there been any attempts to transfer data as sound? I don't mean sound converted to electricity, or to represent 0s and 1s, but using a specific frequency range to represent 1, another range to represent 2, another for 3... I don't know the terms for these things. Using vibrations instead of electrons to transmit data over a wire? Do creatures like dolphins do this?
Frequency-shift keying?

(The 0 and 1 version is binary audio FSK, but you could also choose to have more frequency levels, such as 4 or 10 or 20 different levels.)
People studying this don't usually distinguish between whether the waves are emitted into space as audio or whether they're encoded as electricity. The main reason for that is that we have devices (speakers and microphones) that convert directly between audio and electricity in both directions, so the design of a system that uses a wave represented as electric signals and a system that uses a wave represented as sound is "equivalent" in some way (even if they face somewhat different practical considerations, like different kinds of background noise).
Edit: oh, there's a more detailed Wikipedia article on non-binary FSK, called "multiple FSK".

It gives some examples of practical applications of this (again, not distinguishing fundamentally between what kind of waves you use).

With this headline, I cannot hear anything in my head except “the dial-up noise.” TCP over sound was how I used to connect to the Internet…

Good catch, but it was actually over audio signals. Sound was just for monitoring.
I think one was used in the film War Games, but can't recall clearly.

I wish there was a youtube link that demo'ed this here :)
