Since the main (but not exclusive) use of non-US right now is for crypto software, we might want to create a Crypto-Regulations package which contains references to which countries restrict import and export of crypto, and how, with references to appropriate legislation and documentation.
This would save every maintainer of a crypto package from having to go hunting down the information, and in fact could be made a part of Debian Policy for crypto packages to respect it. Don't think of this as added work: think of it as doing right something which has only been half-done up to now. The US is not the only country with restrictions on software. Our source of possible countries in which to host our non-US mirrors seems to shrink every year. Jonathan
