title: Hide content from non-fans in a Facebook *IFrame* (Not FBML)
body: <p>it is incredibly easy to hide content from someone who does not like your application...if you're using FBML. I'm using an iFrame and the JavaScript SDK, and am having terrible difficulty figuring this out.</p>
  
  <p>The behavior I'm seeing (both logged in and out) is that does not seem to be supported by FB.XFBML.parse(). Am I mistaken or is there an alternative method I can use that does not require the user to give explicit permission?</p>
