i've had to deal with situations like that before, not specifically because of gpl but because of international regulations. one of my customers was a digital id provider, and they had one of those super-accurate timekeeping/cryptography servers they needed to move from lithuania to sweden. because of laws surrounding encryption of personal information, the server would count as compromised if there was ever a single second where it was left without supervision. so they had two of their people drive non-stop through poland, germany, denmark and half of sweden with the server on a ups in the back seat.
