%) good one..

Here we go again..

Section 2.3:

The draft should probably state that the IV should always be a multiple of 32 bits.
Or require multiples of 64 for IPv6.

Section 2.4:

To solve the alignment problem, could we always simply require the replay field. 
Don't use it if you don't have AH but leave it there with random trash otherwise
to preserve alignment.  I don't believe I'm saying this... %)
