Does CC-SA require a modifiable copy?

It would be an interesting edge-of-the-envelope case
if someone distributed a work CC-SA, but the only way
to use that work was through the purchase of their
software package for $199.
If Poser handed out 3-D models for CGI stuff, but they
were all in the Poser format or something.
I suppose it would simply push Blender to move to support
that format or something.
CC-SA intends for anyone to be able to sell a work for profit.
I don't think distributing a work in a proprietary format
so that only you can make money from it is really the spirit
of that license.
If that's what you want, be straight about it by using CC-SA-NC.
Personally, I hate SA-NC, but better to be honest up front than
to say "our stuff is CC-SA" but then have it in a format that
requires the purchase of your software to use it.
