remotely wake a napping system - Server Daemon

 PowerWake Server is a mechanism to remotely monitor and wake up systems
 based on manual intervention, or automatic intervention based on a set of
 monitors.
 .
 PowerWake Server can monitor:
   * PowerNap status (online, powersave, offline)
   * Network activity (ARP activity for a given set of hosts)
 .
 When activity is received, the monitors will automatically try to wake up
 if it is in powersave or offline mode.
