Hey,

the plan for 5.4 is to ensure it works well with WebView (and hopefully 
WebEngine as well) - so locally. But thanks to WebSockets, you can talk to 
arbitrary remote clients as long as they support WebSockets. NodeJS should 
thus be pretty trivial, I simply never tried it out so far but I don't see any 
problem with that.

Regarding QML client and QObject backend, that should work the same way. I 
just refactored the code yesterday and ported the unit tests such that they 
run the qwebchannel.js code inside V4. So you can setup a JS web channel in 
QML just fine and get objects somehow, e.g. again via websockets. What's 
missing here is an implementation or auto-wrapper of QQmlWebSocket for 
QWebChannelAbstractTransport. That's trivial to do though.

Bye
