Why not just use write(1) on any prompt to chat with other user logged into a normal shell?

I can't imagine there's much benefit to it or that the goal was to be better than the existing inter-session tools in Linux.

But I built an ssh server in go once, which was a fun way to learn the deeper features and flows of the SSH protocol.

I think it's cool to see someone else doing something similar. Like affirmation that my curiosity (and maybe some stumbling too) is something worth cultivating

Dedicated constrained-use service.

The chat server permits chat, but no other shell functions (one would hope).
