This would be a feature I would like to see.
At the moment, I am scheduling WHS to shutdown via task scheduler and using shutdown.exe in c:\windows\system32 however, as yet, I haven't been able to get WOL to work but I think that may be the network card.
An "easier" way to do this would be better, as the last comment said, perhaps using the console to be able to wake up a WHS.
