title: Invoke pusher when mysql has changed
body: <p>How possible is it to get <code>mysql</code> database changes to be pushed to a an admin screen without admin interaction using <code>pusher</code>? </p>
  
  <p>Can <code>pusher</code> run some kind of listener for changes on the <code>mysql</code> or will <code>pusher</code> simple do some kind of fancy polling?</p>
  
  <p>All in all how would such a setup be coded? </p>
  
  <p>A simple example or a link would be very much appreciated.</p>
