Paypal doesn't support multiple websites for its IPN (1 url per account and they don't allow multiple paypal accounts).

I found this nice little script for a ipn broadcasters

but the only thing I can't locate is where the paypal ipn.php reference is in X-cart to modify this script. Anyone have any experience in this?

The script is basic. You point the paypal IPN url to this broadcaster script (as a php file on your webserver) and define

  /* List of IPN listener points */
  $ipns = array(
      'mystore' => 'http://mystore.com/ipn.php',
      'myotherstore' => 'http://mybigstore.com/paypal_ipn.php',
      'myotherandbetterstore' => 'http://slickstore.com/paypal/ipn.php'
    );

as your paypal ipn listeners and it will broadcast the ipn to all your stores so that whichever one is valid will receive it and complete the order.
