Ah-ha!  Now I see what Erik meant.  Just to be clear on terminology,
AFAIK Amundsen's requirements go *far* beyond the conventional
definition of "hypermedia"
http://en.wikipedia.org/wiki/Hypermedia
as Amundsen's requirements are all about supporting hypermedia
*applications*, which of course is what we want to do with LDP and
Hypermedia As The Engine Of Application State (HATEOAS)
http://en.wikipedia.org/wiki/HATEOAS .
Mike's H Factor summary is excellent!

Very nice!  It looks like an excellent direction to me!
