If you're an #Emacs user, please do yourself a favor and check out CRDT. It's simultaneous editing on multiple devices, including mixing GUI and text editors.

I absolutely love this thing: https://elpa.gnu.org/devel/crdt.html

GNU-devel ELPA - crdt

@mattsheffield It supports the tox protocol, I thought it had died! Really cool tool, if I understand correctly it allows async collaborative edits.

@lf_araujo Yes, although it isn't usable offline unless you're on the server side, and I couldn't get the TLS tunnel to work for me. Works fine through an SSH tunnel though.

I've long used daemon mode for multi-device editing, but it didn't support using a GUI client, which is often helpful with huge files. This is my Emacs holy grail, can't believe it's been out for a few years!
