Not sure. You certainly need to include the individual copyright
notices (*), just including one copy of the permission should be
enough.

I read the book of Larry Rosen, and his opinion is that software 
engineers should stick to software. Licenses is the field of
lawyers. So if in doubt, ask the foundation's lawyer, and he
will tell you what to do (although you may need to learn how to
ask a lawyer first :-)
