I have two questions where it's not clear to me if this
specification does or does not introduce new vulnerabilities.
It could well be that it does not and these are handled
elsewhere, but I'm not sure so...

(1) How is authorization for being a member of an RBv handled? 

(2) If a rogue RB can add itself to an RBv can it arrange
things so the rogue RB becomes the DF for the RBv?  (If so,
that would seem to create new DoS opportunities at least.)
