The goal is Grids of Characters
This is the main tenant of the text display on the client side.
The client being safe viewing down to a TI-84 calculator.
That isn't a requirement, but the markup text makes this simple enough to implement
into a protocol string in my noob opinion- it should be curl-able actually if your
other end was running the service and display could handle it.
I am new to all of this, it is all word soup to me.
I will do best to not butcher terminalogical items, but one should get where it is going if it is
something interesting enough to them.
Internet of things level I think
I believe there are enough public wi-fi locations to run a simple public facing server on a vps, and have a simple text chat between low level tech devices, like RPI0, something conceivibly solar powered and runs a lean ass OS with the minimal browser to access the means of entering text, displaying it on the spec't grid (which is fully negotiable on both sides with this).
