If you can stand hearing 1070Hz, 1270Hz, 2025Hz, and
2225Hz tones,
and you're not making too much noise,
I might nt be making much noise, but the fans and hard drives in my
classics are hardly silent...
howzbout: implement Bell 103 with modems with
microphones and speakers,
and just skip the whole interconnecting wire business. You'll be able to
keep track of the transfers, and prob'ly even have fewer people coming
around to waste your time.

However, one reason to avoid wires to to avoid upsetting Pentina the cat.
I think your proposed solution is likely to really other him, alas.
