I was messing around with a terminal server, I liked being able to access my home server's and managed switch's console/rs-232 port over telnet. That got me thinking, though.

Does it just have to be text/consoles that can be accessed over the network? What if I connected some other serial device to the terminal server?

I decided to see what would happen if I connected a serial mouse and tried to access/read it over the network. Long story short, I wrote a small python script to let me read a serial mouse over the network on Windows (and Linux, but on Linux you can just use socat and inputattach).
