@kalisp had a stab at this and it's proving quite difficult, maybe even impossible right now, we'll have to do more research, if it becomes higher priority. Currently it's not crucial.

Summary of current state:
Harmony uses QtScripts which is based on Qt 4.8. That version doesn't have support for websockets. Qt own https://doc.qt.io/qt-5/qtwebsockets-index.html are present only after Qt 5.3.

I tried to hijack couple of libraries from Node.js, but they depend on features of ECMAScript v6, QtScripts is on 3.

Whole QtScript is actually obsolete and unsupported by Qt for a while :(.
(In PS current implementation works as they are using some browser js engine, so Websocket API is implemented by default and our used js library just extend that.)

Could the communication from Python be the websocket?
Then just implement an interpreter in Harmony.

This is now stabilized in ynput/avalon-core#211. It is still not ideal as 100% websocket server would be really cool, but with limitations of QtScript it is not worth to do it.

Closing this down as it is not really needed and too much hassle for little return
