I suppose it depends on what you call sending a message. email works for most of us. You can ssh between hosts, but to message people youu need to find specific tty names as well. If you want them to reply, you need some sort of artifact there for them to send through. I once tried something with mmap() atached NFS files, but changes were not picked up unless I did an ls on the end remote from the write. Maybe if everyone tailed a file and wrote to that file under an id header line in tight blocks, you would have a logged chat session. I have done that. If you have no NFS, you can "ssh ... tail -f chatfile &" to see the dialog on one xterm and do an ssh to write blocks from another. You write blocks by composing them in an env variable and then echoing the variable as one atomic write. Oh, I said that word, but the command is echo not write.
