title: nowjs - refusing a client connection
body: <p>i've got a nowjs question:</p>
  
  <p>how do you refuse a client connection from the event handler for the connect event?</p>
  
  <p>i'd like to check some values on the server when a client connects and then decide if i drop the connection or let him connect.</p>
  
  <p>ok, since stackoverflow somehow thinks my question is somehow below their quality standard, i'll try adding a code sample...</p>
  
  <pre><code>everyone.on('connect', function(){
      if (!niceClient) {
          // do something to kick him out
      }
  });
  </code></pre>
  
  <p>thanks in advance!</p>
