title: Distribute iPad app outside of Appstore
body: <p>I've developed an app for a company that doesn't want it to go on the appstore.<br>
  I just built it on each of their iPads and gave them back, but a year after I had to rebuild all of them, due to some licence restriction (I imagine)</p>
  
  <p>How do I go about putting it on their iPads without having to reinstall every year :)?</p>
