title: A device to device push notification system
body: <p>Well, my idea is to make an app that is installed on two or more devices.  The main or "head" device can send out a call to one of the specific devices in the form of a push notification.  The push notification could be preset or whatever.  The goal would to be a simple notification system.  All of the users who I am making this for have an iPad active and sitting on a desk in front of them.  Imagine this as a doctor tool for calling the nurse into the room when the patient is ready.  Tell me if this is clear enough.</p>
  
  <p>How would this be done?  </p>
