NCSA is doing collaborative work with the Hyper-G people at Gratz University
in Germany.  What do you want to know?

Their URL is : http://hyperg.iicm.tu-graz.ac.at/Chyperg

(Note:  I tried to check the URL since I haven't been to the Hyper-G
site in a while, but the download was slow enough I had to leave for
a meeting before it finished.  My apologies if the URL is no longer 
valid.)

They have a lot of nice features.  Their biggest problem lies with
scalability.  Since every server knows about all the documents in every
server it is easy to maintain consistency, and provide link maps, but
it just doesn't scale well.  The client uses a session manager which
brings up windows for each service requested.  You can link a jpeg,
audio track, and document together to be a single object.  They do
content negotiation on at least the language field and some other
fields.  We've modified some of their code for use with some of our
client applications so we both can embed links in video now.  I think
some of their viewers are being modified to work with Mosaic.  To
reach WWW a Hyper-G client goes through an HTTP gateway.  The Repository
project has been trying to include several of their ideas.
