Bart Van der Donck has released his script to do Ajax Cross Domain scripting. You download the ACD.js script and then you can do things like this hello world:

PLAIN TEXT HTML:

<script type=”text/javascript” src=”http://www.ajax-cross-domain.com/cgi-bin/ACD/ACD.js?uri=(http://216.92.176.52/?name=john)”></script>

<script type=”text/javascript”>alert(ACD.responseText);</script>

Here is how it works:

I love how the learning curve has been defined for you to Bart :)
