Re: (LONG) Correct non-US solution
As a practical matter, I don't think any countries restrict
importation of software that might be in Debian, unless they also
restrict its use. The only such circumstances I can think of have
to do with pornography; in the UK, for example, customs will seize
things that are on sale openly in London. But I don't expect there
to be anything in the Debian main collection that would be objectionable
on those grounds.
Both in the case of encryption and in the case of patents, the
countries that restrict import also restrict use.
Also, I am not sure it is useful to distinguish between
"use-restricted" and "patent-restricted", given that the consequences
would be the same.
However, making the extra distinctions won't cause any harm
if people want to do that.
