I use emacs as a daemon and attach to it via emacsclient. That makes it persist across disconnects.

I also spawn all my shells inside emacs, which gives it tmux functionality.

I've submitted a request to have you banned. Look at your history. You contribute nothing and just spew annoying nonsense. Adios.

Sure it can. Why couldn't it? At worse, you could write a multi-threaded C library and have emacs/emacsclient call into it.

That's why I said that model needs to be extended. There's no reason emacs server couldn't send stuff over a TCPsocket to emacs client. Emacsclient and emacs server are separate OS processes, so they already communicate via external mechanisms.

I almost exclusively use emacs --daemon and then emacsclient to connect to it.

In my opinion, this model needs to be extended so that emacs daemons can't accept connections over a network. Maybe piggybacking SSH, or some other socket protocol. Of course, never could administrators would have to enable that port, so there are complications in professional environments.

He's talking concept and you're taking implemenation.
