The reason I am interested in doing this (sometimes) is not really for
latency.  A human doesn't really cause any problem for a real-time system.
My thought is that packaging could be a lot better because nowadays you can
mount a PC on the back of a monitor, feed it power and ethernet and be done.

My obsolete desktop runs latency test just fine with 7uS of latency with
the craziest loads I can put on it.  I see no reason to worry about
latency.  I doubt I will run youtube on my mill that often, although my
worst crash when I was trying to use Windows for machine control occurred
because Bill Gates chose to check my email at an inopportune time.
