I would appreciate it if you could provide the type of constraint
networks/devices and the use cases you have in mind as input for
discussion.

Our aim is to look at the use cases and requirements independently of
existing protocols. We might highlight gaps in existing technologies but
selecting the right protocol is an individual decision. 

Cheers,
