This works now and Ricardo has tested it. The remaining bugs in WOL don't 
affect it.
B.t.w. this should be re-phrased as ARP requests for XO's own IP address.


Can you update the trac?

Again, WOL works as it is supposed to be. The WOL filter wakes up the 
laptop when it receives a frame destined for a multicast address that the 
network adapter listens for. That means that as we stand right now the XOs 
will wake up on reception of every frame destined for the presence 
One way out of this would be to stop the presence service before going to 
sleep and starting it up again upon coming out of sleep.
In that manner presence updates won't wake up the XO, but traffic destined 
to already running activities will.
