Node WOL on receiving render job

Hi,
I can wake a node up from sleep by pressing the wake up button. However, it would be great if nodes would automatically wake up on receiving a render job. The render nodes could go to sleep (and therefore save electricity) when not in use and come alive when I need them. Possible? Good idea?

Hi!

+1 on this request, especially with current electricity prices this would be a game-changer. Option to shut down specific nodes automatically if they are not rendering and sending WOL packet when a job is in the queue.
