I've used a machine fitted with an electronic handwheel and a joystick next to
it.
The joystick could be set to given feed rate, it also had a small button in the
end of the stick to over-ride the set feed rate- useful for rapid traverses.
Yes the joystick could be dangerous, but so can an incorrectly programed G code.

My choice would be a joystick and a handwheel, both with programable feed
rates/resolutions. Just a thought - a feed back loop so the handwheel feels
like it is connected to the feed screw !
