Paypal multiple IPN and or PDT

How do I set up nopcommcerce to work with Multiple IPN's on paypal?  I already have a store using Paypal and don't want to cause problems with it.

Thanks

I may be mistaken but I believe Paypal does not support this. You might want to contact them about it.

Paypal does support this but you have to send the IPN URL with the paypal submission - as in the following from the Paypal site:

PayPal handles this, by allowing us to add separate “return URL”-parameter in the PayPal form value set going from our apps to PayPal like this:
<input type="hidden" name="notify_url" value="[YOURSITEURL_WHICH_HANDLES_IPN]">
<input type="hidden" name="return" value="[YOUR_SITE_URL_WHICH_HANDLES_RETURN_URL]">
<input type="hidden" name="_notify-synch:cmd" value="_notify-synch">\

Does anyone know if Nopcommerce can do this?

I found a solution. You can ask Paypal to setup a child account which will have it's own IPN/PDT but work with the same bank account etc., as I understand it.
