As someone who just retained legal help in this area, export control is not as simple as many of you make it out to be. An export happens when material ends up in the hands of a foreign national, whether it's inside the border or not. Businesses have an obligation to "know their customer" and look out for "red flags". I'm not an expert in this area. It's just as I have had to delve into it, it's nowhere near trivial or as easy to deal with as you might think. Oh and the fines for being wrong (even if you self report) can be very very hefty.
