title: Access Dropbox files when iPad is offline
body: <p>I'd like my native iOS app to be able to access all my dropbox files on my iPad when the iPad is offline.  I have played with Dropbox's Roulette app but it seems to stop working as soon as you go offline.</p>
  
  <p>Is it possible to build an app that integrates with Dropbox and which will access the offline Dropbox storage when the iPad is offline? </p>
