Can you let us know whether the CC-by-SA 4.0 license is acceptible

merge window. If not, we'll go back to the drawing board....

I remain pretty concerned about it, to tell the truth.  Rather than
continue to guess, though, I've called for help, and will be talking with
the LF lawyer about this next Thursday.  Before then, I can't say anything
except "I don't think this works..."

Will let you know what I hear.
