title: Only one connection at a time in phpwebsocket
body: <p>I am playing with <a href="http://code.google.com/p/phpwebsocket/" rel="nofollow">phpwebsocket</a>. Is there a way to have only one user connected at a time?</p>
  
  <p>If a second user tries to connect they should be automatically disconnected and if the first user is idle for a given amount of time he should be disconnected to allow space for a new user.</p>
  
  <p>Is this possible - and if so, does anyone know how?</p>
