If our license speaks systematically of "the Library", it makes no
sense to allow 0MQ to be used otherwise, and indeed the conditions of
COPYING.LESSER cannot even be applied (i.e. it becomes impossible for
a user of a 0MQ-based product to modify the 0MQ library, which is the
goal of the LGPL).

If someone takes the 0MQ code and removes the library aspects, and
redistributes under the GPL, that's fine, but it is not (and may not
be called) 0MQ.

Totally, but that's not our project.

Yes. The alternative is to change the copyright statements file by
file as the sources change but that's more work.

I've already done this for ZFL.
