i don't think gnu/open source software can be restricted by US or UE (or any other country for that matter). isn't this US (land of the free that wish to free the oppressed) law restricted to companies and government institutions? thou i think i can answer one of your question, maybe with another question: what encryption? you have all the source! no "proprietary" software here. anyway like linpf "I am very curious on the status/prospects of Linux usage in China. " and specially this question!
