So the use case is:

User is part of a multiparty (3 or greater) session, but for one of 
several reasons (such as
available upstream bandwidth)  cannot send media to all other 
participants ("mesh" conferencing).
This requires that another node, either a central network node (such as 
a conferencing server)
or another member in the session, relay or mix the user's media to 
distribute to the rest of the
members of the session.
