CoVim

I don't want tmux. I'm sure that's going to be the #1 suggestion so I'm putting this statement at the very top to hopefully prevent those. Please read on. In case it's relevant, host and guest are both on macOS. Things I want: 1. multi cursor (each user can edit simultaneously) 2. each user has their own keybindings, theme, etc so that the guest doesn't have to guess the host's keybindings 3. super-fast 4. decentralized for security purposes. In other words, nothing is sent to another party or server 5. prefer something free 6. not require creating an additional user in the OS (thinking of tmux here, to do things safely you should create a restricted user that your guest ssh into) I'm aware of: * [TypeInTandem](https://github.com/typeintandem/nvim). Might work? Haven't dug into it yet, though their website http://typeintandem.com/ can't b

I think this isn't being currently worked on, although the author notes that NeoVim (and, lately, Vim 8) may have the tooling to allow it to less difficult to develop. https://github.com/FredKSchott/CoVim/issues/86

When Vim is inactive, I can attach a function in a CursorHold autocmd event which would consists of loop that reads from the resource object and sleeps for a small interval after that. As the external program/socket connection is running in separate process, reading from it is not resource sensitive so it should not block Vim entirely. BTW there is a plugin called CoVim https://github.com/FredKSchott/CoVim that implements pair-programming feature using default built-in Python binding.
