title: Open Source HTML5 Online Powerpoint Viewer
body: <p>I wondered if anyone is aware of any online powerpoint viewers that are open source?</p>
  
  <p>I've looked at <a href="http://www.accusoft.com/products/viewer/on-premise/info/overview/">http://www.accusoft.com/products/viewer/on-premise/info/overview/</a> which is the closest thing but it only works with web based documents, mine will be sitting behind an intranet firewall so now I've hit a blank.</p>
  
  <p>I've tried ViewerJS but this doesn't support PPT.</p>
  
  <p>If anyone could help me out with a js ppt viewer that is open source or has any other ideas then I would be very grateful</p>
  
  <p>Regards Sam</p>
