Our previous cart application was able to avoid this even being a possibility by passing the invoice number along with the DoDirectPayment NVP call, which triggers a duplicate invoice check with Paypal. We do have invoice numbers being assigned (same as the Order ID), but from looking at the Paypal Pro plugin, it appears there no way to actually associate that with the paypal transaction, since the payment is entirely handled during an onBeforeCreate action, which means the payment is complete in its entirety prior to an order number even being available.
