Internet Relay Chat

Definition and stakes

“ However, the party at the other end will have to have the same program online for the connection to work.
11.2 INTERNET RELAY CHAT IRC is a program that lets you hold live keyboard conversations with people around the world. It's a lot like an international CB radio - it even uses "channels." Type something on your computer and it's instantly echoed around the world to whoever happens to be on the same channel with you. You can join in existing public group chats or set up your own. You can even create a private channel for yourself and as few as one or two other people.

“ Generally we hung out in Internet Relay Chat rooms. (They’re sort of a window – a chat room – where you can see who else is there and anybody can type anything into the group conversation.) And so, many years ago, there was a Semantic Web Interest Group chat room. ”

“ In other words, you could have the same conversation over IM as you do over SMTP. With the right tweaks, the whole mail-server business could take place inside of a chat. Or a web-session. Or anything else.
This is called "tunneling." You put the SMTP inside a chat "tunnel." You could then put the chat back into an SMTP tunnel if you wanted to be really weird, tunneling the tunnel in another tunnel.
In fact, every Internet protocol is susceptible to this process. It's cool, because it means that if you're on a network with only Web access, you can tunnel your mail over it.
