The "share alike" provision in the plain english text says:

"The licensor permits others to distribute derivative works only under a
license identical to the one that governs the licensor's work."

The word "identical" seems a bit strong to me. Isn't the real issue to
prevent people who make a derivative work from issuing a much more
restrictive form of license (like full copyright)? And if so, wouldn't you
want some kind of license that would allow derivative works to be
distributed under "similar" conditions? For example, it is hard to imagine
that any author of a work distributed under a "BY-SA" license would be upset
to see a derivative work distributed under "BY-NC-SA." Same for the
incorporation of BY-SA content into a GFDL licensed work. But the current
text of the BY-SA license seems to forbid such things. Or am I confused?

If I'm not confused, would it be possible to create a new license or change
the existing "SA" portion to take this into account? Maybe by exhaustively
listing compatible licenses? Or by giving people the option of listing
licenses they feel meet the spirit of "sharing alike"?

Thanks for the great work being done here!

Hi Chris,

This is a good question. More below.

We're working on just this issue, among a couple of others, in our
versioning research. Not sure yet if the answer is the exhaustive list
you suggest, or something more-open ended, but I can say that we plan to
address this (to account for compatibility across our iCommons licenses
and other "share alike"-friendly licenses). So stay tuned!

Thanks for writing in and glad we're on the same wavelength.

Glenn
