title: Cross-domain AJAX - would this method work?
body: <p>I've been thinking for a while if there's a way to get cross-domain AJAX (using XML, not JSON) to work. Can anyone see any reason why the following wouldn't work:</p>
  
  <ol>
  <li>Create an iframe  </li>
  <li>Load the URL of the AJAX call in the iframe  </li>
  <li>Use JavaScript to get the content of the iframe</li>
  </ol>
  
  <p>(this won't be asynchronous, but could using <code>setTimeout(functionToLoadTheIframe, 1)</code> enable you to achieve asynchronicity?)</p>
