Hi Brad, I think you'll find it's a lot more contained than you think. 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.
