title: Android Market subscription payment model. How to?
body: <p>I would like to have two apps. One to do the real job and another one to carry the payment on a monthly basis (licensing app).</p>
  
  <p>Users must download the licensing app each month from Market. But, should they have to uninstall the last month's app before that?</p>
  
  <p>Can an app auto destroy itself (uninstall itself)?</p>
