Sorry that I don't yet understand what you meant. From my standpoint
I have designed a certain protocol that is intended to serve a certain
purpose. Thus IMHO what has to be discussed/debated includes: (1) Does
the protocol correctly function? (2) Is it new at all? (3) Are there
better (more efficient) protocols. There may be generalizations that
achieve much more than what I had in mind, but that's beyond my current
personal interests/capabilities.
