Hello Alex, That looks interesting, nice to see the separation of concerns. I wonder if emcrsh is all I need, just build a little web socket server that ties into a telnet session.

Take a look at halui.cc (which is one of the most simple UIs, although not a GUI). You'll see that all the UI does is send commands to the task controller, and from there things get routed to motion, io, interpreter, etc. (of course the theory sounds a way lot easier than it is in practic, but it's not that bad either). There is also emcrsh which allows one to control linuxcnc through a telnet session.
