The team behind this feature think that editor-agnosticism is also really important, that's why they split up this project into atom-teletype and teletype-core. AFAICT the 'core' library could be used to implement a package in any of the electron based editors.
Could the protocol implemented by teletype-core be (easily) spoken by a non-electron editor, or is there an inherent impedance mismatch where e.g. the protocol structures its data in ways amenable to DOM manipulations of text but not to other text buffer formats?
The protocol isn't coupled to the DOM or Electron in any way. The one thing that makes it easier to implement in electron is that it uses the WebRTC standard for peer to peer connections.
WebRTC is a beast of a protocol to implement, and so far browsers have had the canonical implementation. There's a few C++ libraries out there, but even then it's a lacking ecosystem.
