title: iOS and Infrared
body: <p>Is it possible to communicate with an Infrared device (USB Infrared, TV, Mobile Phone, etc) using iOS (iPhone or iPad)? </p>
  
  <p>Well, i know it's possible, since there are many remote/universal remote applications in the AppStore. I basically want to know how? </p>
  
  <ul>
  <li>What are the limitations and
  requirements?</li>
  <li>What kind of additional hardware is
  required? If it's available in the
  market?</li>
  <li>Which protocols should i know about?</li>
  <li>Which iOS libraries can help me in
  the process.</li>
  </ul>
  
  <p>Can anyone point me in the right direction. Thanks.</p>
