Should be possible to create something that pushes the powerbutton, waits for power down, pushes the power button again, waits for power up. And at least for a German kid growing up with both, I'd just love to see that in action :-) Both Lego and Fischertechnik offer pneumatics and computer interfaces, and some sensors.
