You Dad's product being physical is not a sticking point ... we aren't biased towards physical products, it just so happens that the majority of our merchant partners sell digital products ... import/export topics the nature of which yours covers may be few and far between, though I'm sure at least one of our partners has experience in that area.
I recommend you contact Dr. Amit K. Chatterjee <amit @ infobanc.com> of www.infobanc.com/ ... a true expert on the topic.
