Any license containing the SA clause requires that derivative works use
the same license. Derivatives of a BY-NC-SA work will carry the same
license, which requires that derivatives thereof do likewise, ad infinitum.

This, I don't know. I would think that derivatives only have to
attribute the work(s) they directly derive from (which in turn attribute
works from which they derive) -- not to carry forward all upstream
attributions.

I am not a lawyer, and I will leave it to the others on the list to tell
me if I'm wrong  :)
