Agree with the direction toward group communication. This roughly aligns
with goals of 
<https://datatracker.ietf.org/doc/draft-hardjono-ace-fluffy/> which is
inclusive of group key management for symmetric. Fluffy has broader key
management goals, but symmetric group key management is a great place to
start. 

It also aligns with directions the OCF are heading as they see value in
the use of group keys for doing secure discovery.
