I was wondering if anyone knew of an affiliate program script that had the ability to utilize Paypal for tracking both sales AND affiliate payouts?

I have a couple of really popular mainstream products right now that id like to open up to others to promote on the non-adult boards i post on.

Does anyone know of an affiliate script that has the ability to track sales made by PayPal and also do affiliate payouts through PayPal automatically whenever a sale is made?

Regards,

Lee
