title: customed message for a specific person via GCM(google cloud messaging)
body: <p>just I want to ask you about <strong>GCM technology</strong>,I have to use it for my client in his application(college application). So my question : Is it possible to send a message for someone let's say a professor working in that college(Hi Sir, please you have to be present in administration today at 9 Am), of course as I said just for <strong>one professor</strong> not all the users application !!!</p>
  
  <p>my idea here is to pick the specific professor from the listview of all persons in that college (by fetching the database) and send to him my message as <strong>push information</strong>  . 
  just I want to note that I'm using <strong>python</strong> as <strong>backend language</strong> and <strong>Android</strong> as <strong>client</strong>  </p>
  
  <p>Is my idea valid or should I see another way ???
  thanks a lot.</p>
