title: Facebook js api: share a post to a friend's wall
body: <p>i really hope, someone can point me into the right direction. I am ordered to write a drawing game for facebook. The concept is, the one, applying for a win, references a friend for the prize (the player won't win anything, just his friend).
  The customer want's a Post on both Walls/Timelines. AFAIK it's not possible to post on the friend's wall. Right now i am as far, that the App posts on the wall, of whom is playing.</p>
  
  <p>Is it possible to share this Post to his friend without any Dialog or represent to the friend, that he is applied for a prize?
  The customer wants that this doesn't use any share/feed dialog.</p>
  
  <p>Thanks in advance</p>
