licenses of derivatives are always
equal to or more restrictive than
the license for the original.
You cannot take a work licensed CC-NC,
create a derivative of that work and
license it CC-PD.
The only thing that ShareAlike
changes in this equation is that
derivative licenses can only
be equal to teh original license.
You can take a CC-NC work, create a
derivative, and add attribution as
another restriction, ending up with
CC-NC-BY.
If you take a CC-SA work and create a
derivative, you cannot add any restrictions,
you must license the work CC-SA.
But nothing allows you to create a
derivative of someone else's work
and license it less restrictively
than the original.
Well, nothing excepting contacting the
author and getting their permission.
