title: Self-destructing application
body: <p>Along the lines of <em>"This tape will self-destruct in five seconds. Good luck, Jim"</em>...</p>
  
  <p>Would it be possible for an application to delete itself (or it's executable wrapper form) once a preset time of use or other condition has been reached?</p>
  
  <p>Alternatively, what other approaches could be used to make the application useless?</p>
  
  <p>The aim here is to have a beta expire, inviting users to get a more up-to-date version.</p>
