This is already a problem for lots of other things, so it is not unique. I worked in a oil service company in Norway and we always had a lot of crap to deal with to make sure nothing when we sold our software to Iran, no American was in any way involved in that process. That is difficult when you all work in an office with people from lots of places, and you are used to sharing information and working together and suddenly you have to be conscious about the citizenship of some of your colleagues.

There are already a myriad of national difference you have to deal with, accounting rules, rules on corruption and bribes, which country has which patents etc. Privacy just seems like any other item on that list.
