I'm not qualified to comment here, but; With the continual difficulty with video drivers and other bits affecting latency, who not split the the functionality. I don't mean a headless system, just extending the neck. A partial mitosis.
This way, the motion controller part will work on almost any pc(video disabled), and the UI will work on almost any pc(serial connection between machines) Nor is this not a drip feed system. It's a matter of taking a complete program and splitting it into two, with a serial connection for comms. I really don't think any hobbyist has a shortage of pc's. So now the one half becomes a motion controller, nestled in the guts of the machine, as it should be, and the other half can be on a boom or at a desk. I see Kirk was going this way in 2007, but I don't know if he completed it. So it can probably be done art the moment, but I mean doing it as a strategy, in the sense that it becomes the norm.
