I'm willing to try.  (And I've already signed over copyright for my own 
FSF contributions.)  Actually I believe that some of the authors should 
have papers on file already.  Who would I contact at FSF/records to 
verify this?

Note I assume you are talking about the case if we go the route of 
updating the ns-emacs codebase to 21.  If we go the route of starting 
from the Carbon-based version, it is OK copyright-wise to use the 
ns-emacs code as a reference as long as major chunks are not copied 
directly over, correct?

Is there a summary available anywhere of what the main internal changes 
to display management were?  I know that, functionally, images, 
proportional fonts, and the fringe are the main additions.  But maybe 
there was significant internal revamping?  (I know I can just go and 
peruse the code but it might save some time to have a little 
guidance..)
