Erik, great points and suggestions.

Mike, this would be fantastic. One of my concerns with the current
CC BY-SA is that any time I feel like using such a license, I really
want sharealike to mean "derivatives must grant at least the freedoms/
rights granted by BY-SA, and pass on this clause"... to allow for the
derivs to be BY / PD / &c.
