title: Distributing (and updating) an enterprise Android application that is to be used in-house only
body: <p>I'm building an Android application for an enterprise customer that will be used in-house (and not sold). Though we have additional auth measures, I'd rather not deploy the application on the marketplace.</p>
  
  <p>I was just wondering if anybody had previously done something of this sort, and had suggestions.</p>
  
  <p>Also, If we were to upload the APKs, how could we handle updates to our software? As I understand it, the Android marketplace handles update notifications if the Marketplace is used. Would we have to write a service of our own to monitor for updates?</p>
