I don't see how it can conflict, there is not index file included in the AjaxFw package.
For an existing installation of CI, just do exactly the same, unzip the plugin and drop it inside the cjax/plugin directory, and that should be all, I think.
Do this in your Controller:
Code:
require_once "ajaxfw.php";
$ajax = ajax();
For Codeignater ajax.php is the file ajaxfw.php, and ajax.php is the integration into CI, as specified in the wiki.
