From the developer:
PowerBlock intercepts and ignores presses of the power button and optionally runs AppleScript. This is handy on the MacBook Air where the power button is now a key on the keyboard and can be accidentally pressed.
By running AppleScript when the power button is pressed, you can setup your system to immediately shutdown, restart, sleep, or eject a DVD when the power button is pressed.
