I think that some GNU-advocates would recommend that
you refuse the
permission they ask for, and instead tell them to license it under the
FDL, in order to increase the net amount of GNU-yumminess in the
world. As for me, it would depend on the context and so on as to whether
I would want to do that.
Thanks Jimmy. I don't think I'm going to insist that they release it
under GFDL. The main reason is that the document (not the Wikipedia
article) contains copyrighted images owned by Cessna and Jane's, and one
nice thing about OpenCourseWare is that they do all the running around to
get permission to use those.
