title: How to display a lightweight web client window with ruby
body: <p>I need to display a web page on a PAL 7" monitor with a Raspberry Pi without user controls (no keyboard, no mouse, just display).</p>
  
  <p>The context is :</p>
  
  <ul>
  <li>Raspberry Pi platform</li>
  <li>7" PAL LCD monitor</li>
  <li>archlinux ARM</li>
  <li>no desktop environment</li>
  <li>xorg or eventually a minimalistic window manager (openbox, pekwm,etc.)</li>
  <li>Ruby language (1.9.3 or eventually 2.0.0)</li>
  <li>webkit or other web engine but html5 compatible (I want to use websocket)</li>
  </ul>
  
  <p>What is the best way to display a web page in this context ?</p>
  
  <p>Thanks !</p>
