Yes, it would be helpful to read both the drafts in preparation for the 
discussion.

Optimized authentication is not a substitute for sequence number obfuscation 
draft, and vice-versa. They offer different levels of cost/benefit, where

Draft                                             Cost        Benefit
====                                            ====       ======
sequence number obfuscation     Low        Medium (does not authenticate the 
complete packet)
optimized authentication              Medium  High       (authenticates entire 
“state change” packets)
full authentication                         High       High       
(authenticates all packets)
