title: protecting adobe air apps
body: <p>I am about to deliver an Adobe AIR app to a customer.
  But it's my first delivery of any sort, I.e. I have
  no experience whatsoever with licensing etc.</p>
  
  <p>Users of this app may or may not be online, so 
  can't count on that. In fact it's 99% sure that
  they will be offline.</p>
  
  <p>Nor do I expect them to very tech-savvy, who will
  spend enough time scouting for ways to "crack" it.</p>
  
  <p>So, is there an okeish type of way to protect this
  app. That is, I don't want people to simply copy
  the installation folder, take it to another machine
  and run it. It should be slightly harder than this.</p>
  
  <p>Oh, and I am also using PHP and MySql, with which
  this AIR app communicates. So anything you guys could
  help me with is very very welcome.</p>
