title: Push to a different beanstalkd server
body: <p>I have set my config to use my local beanstalkd server:</p>
  
  <pre><code>'beanstalkd' =&gt; array(
      'driver' =&gt; 'beanstalkd',
      'host'   =&gt; 'localhost',
      'queue'  =&gt; 'default',
  )
  </code></pre>
  
  <p>How do I push jobs to another beanstalkd server?</p>
  
  <pre><code>Queue::push(function($job)
  {
    // This pushes to local beanstalkd
  });
  
  Queue::pushToRemoteBeanstalkdInstance(function($job)
  {
    // ?
  });
  </code></pre>
