No. 3 (key flow) is a good idea, I think.  As to No. 2, I don't think the 
IETF will be willing to recommend a language.  Also, XrML is being 
addressed in Oasis and ODRL within the OMA (I think).

I'm not sure about file formats (No.1).  Ceratin content types, such as 
MPEG, do have a standard content format, and the metadata is expressed in 
the MPEG REL.

Agreed :)

Agree.  I would roughly equate "client" to  "Terminal".  Earlier in this 
discussion Paul Judge mentioned "architectures" and "secure 
distribution/conditional access".  These seem to be a natural IETF work item.
