Sorry, I guess I didn't make it clear that those were examples
illustrating the need for clear info on how derivative works can be
re-licensed, not actually questions.

OK, so, here's my inexpert analysis. (Note that not only am I not a
lawyer, I'm not even particularly bright. Anyone foolish enough to
take my crack-addled babblings as legal advice deserves whatever
hellstorm is coming to them.)

I'm not sure about all of those. The *ShareAlike* and *NoDerivs* ones
are easy; it's the Attribution, NonCommercial, and
Attribution-NonCommercial that are a little dicey.

OK, thanks. If it gets to Monday and nobody's come in on it, though,
please don't leave me hangin'.
