title: Multi browser window drag & drop interface
body: <p>I'm building a control room interface for a web based vehicle tracking system. The system is built in HTML / Javascript / PHP. The control room will have a desktop extended over multiple monitors with a browser window on each monitor. </p>
  
  <p>What I'm trying to implement in a drag and drop system between the windows. As an example:
  Window A contains a list of vehicles. 
  Window B is dedicated to viewing a single vehicle with live tracking.
  The user should be able to drag a link / image / button next to a vehicle listing from window A to window B to display the selected vehicle tracking in window B.</p>
  
  <p>I know this can be done with a click event and the "target" property, but how do I implement the same thing with a drag and drop?</p>
