This is different but I'm surprised it doesn't mention talk(1) https://man.netbsd.org/talk.1 https://man.netbsd.org/talk.1

  Or write(2) [1]. I was thinking immediately about ntalk though, because its the last time I used such on the same machine (because IRC wasn't encrypted back then). The nice thing about that, is that you can have it listen locally only, and then one needs a user account on that machine. So its great for say SDF but also these larger clusters and all that. And it doesn't do auth; you let PAM or BSD_Auth do that. It doesn't do sockets or encryption, you let TLS do that. And you could just use SSH to get to a secure shell, using tmux and (n)talk from there. Goes without saying (n)talk isn't 5 lines of bash as its written in C.
