It's the third variation that makes no sense to me. I just don't think
that's correct. Jmol is a library. All they are required to do is publish
the changes to the Jmol library. The whole purpose of "Lesser" is that they
don't need to publish their code. That's all. Features that involve "new
ways of communicating with or interacting with ...." where is this last
part coming from: "...new features in LGPL work must work and be
understandable and extendable to another user without access to
closed-source work."? Why do you say any of that? What specifically are you
imagining there? Is that language from the license?
