This is possible - perhaps even trivial.  Of course, when something breaks,
you're off to get a console, whether it's the next office over or a thousand
miles away.

Attached is a modified version of what I use on some of our machines, for OS
only, if anyone wants a "starting point".  It's part of a "larger system" I'll
probably never finish.  It's pretty simple, amateurish even ... no tests, etc.
Since we know it works for us, didn't figure it was needed.

YMMV, BSD license, include #<disclaimer.h>, etc.
