Indeed.  Extremely useful!  I'm gathering this works via an "if there's 
a packet directed at the local machine, wake and ask to process".  
Assuming that's correct, do we have a way to filter out bad actors 
wanting to drain the battery of a given machine?

I can just imagine 30 kids getting together to prank user X by arranging 
to ping her every Y seconds to run down her battery (at ~30 times the 
speed of one of the prankster's machines).  Letting the user opt out of 
the wake-on-lan entirely, or opt not to wake-on-lan for a given 
routing/iptables rule-match would be a useful security measure I would 
think.  Probably too late and too complex an approach, but just a thought.

Just a thought,
Mike
