title: Web 3D GIS solution
body: <p>I want to find a web 3d gis solution which provides:</p>
  
  <ul>
  <li>server software to store and serve terrain and 3d models</li>
  <li>a plugin to display on browsers</li>
  <li>javascript api to interact with the plugin</li>
  <li>deploy on intranet (server and clients do not have to connect to internet)</li>
  </ul>
  
  <p>It seems that Google Earth Enterprise provides those features. I heard that the license was very expensive. I want to confirm that but when I contact their sales, the reply is not from a human...</p>
