My first cut, and I have put this forward before, is that we key off of
a "copyright arising" concept.

If you use my CC BY-SA+ work (to use your terminology here althoug this may
conflict with the recent CC Plus (+?) stuff) then in the case of a non
derivative, if a copyright arises in the work that my work is used in, then
the new work must be licensed CC BY-SA+...

Unfortunately, we will have to word it in some such way as copyrights can
arise even if the creator thinks they are not entotled to one. Correct? And
so they would have to license using language along the line of "If any
copyright exists in this work of mine, I hereby license it under Cc BY-SA+.

We could easily let the work when seperated not be under the license. Along
the lines of how the GPL does.

For those who tink this cannot be done unless the new work is in some way a
derivative, I suggest that this requirement can be keyed to the right to copy
instead of the right to make derivatives. Is that clear?
