title: Flex Mobile In-App Billing/Purchase
body: <p>I've looked all over and found nothing about this topic - For people making mobile app games and want to sell levels or potions or whatnot from within the app, is this supported on Flex mobile apps? Are there plans to introduce it? I've found info about advertisement implementation... is this a possible next step? Do you have to use something like PayPal instead of Android Market?</p>
  
  <p>Sorry if this has been asked, but I haven't found anything yet.</p>
  
  <p>Thanks!</p>
