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.
Could there perhaps be an include file feature for specifying these fields? There needs to be a way for a package to specify additional import restrictions beyond those standard for all encryption software. Many encryption programs can't be imported into the US (and some other countries) because of patents.
