The same way as one who shipped mp3 software.

Of course they can simply remove the code that concerns them as companies
*already do*. They have specialists for this, experts who know the very
complex field of import and export regulation.

Actually this is changing, large corporations stealing photographic
images and the threatening to sue the original photographer is becoming
rather common. I'm sure the same will happen in other fields too. SCO
probably did it by accident, but folks will do it deliberately too.

If you don't believe VFAT is permitted in your shipping locale you turn
it off (actually you cut the code from your source tar before build).
Utterly routine practice every day for companies shipping product into
the USA. Happens with tons of other open source software that isn't
permitted in the USA.

The pragmatic approach would be to either avoid the patent without
breaking stuff (which Tridge hasn't managed, although maybe one day he
might), or to produce something which doesn't break stuff, is reliable,
meets our quality goals but which is alternative and clearly presented as
an alternative - such as Tridge's shortname creating tridgefat variant,
which at least didn't randomly explode users data in new and novel ways.
It still needs to be an alternative not a replacement for the real thing.
