I like this line of thinking.  It is very reasonable IMO to expose the core license *types* to the group, without necessarily exposing all the detailed language of the licenses themselves.

What are the core requirements of the content holders as it relates to distribution?  What are their primary concerns?  Without exploring those concepts, any talk of EME or non-user-modifiable content is putting design before requirements.

Thanks to Duncan for raising this and for Jeff for following up.
