We use remote control frequently on our lab computers for all sorts of
task. One problem we have occasionaly is a student will come in to the
lab, try to "wake up" the computer we are controlling ( just has the blank
screen), when it doesnt "wake up" sometimes they will press the reset
button to reboot... killing our remote control session

Is there a way to push a message onto the blanked out screen?
Something like, "System is being serviced - please do not touch"
Im sure this would keep "most" students from messing with the controlled
