Due to the possible legal risk for your users in Europe and Japan it's
still required to keep LZW code out of main.
I'm quite sure we have cryptographic software in main that is
patent-encumbered and illegal for other reasons in many non-US countries
worldwide. Isn't this exactly the same thing? It's been rehashed many
times.
As far as I understand, at this point, the conclusion is that some
patent-encumbered software is still allowed in main, as long as its
distribution does not become "problematic" (Policy manual 2.2.3). How
many countries need to have patents on a given piece of code before it
becomes "problematic"?
I'm quite sure debian-legal will have more to say on this point.
