Re: replay field size

[Stephen Kent <[e-mail]>]

Rob,

	The field has been proposed as an option, not a requirement (though
compliant implementations would be required to support generation and
processing of the option.  As you observe, to simplify the alignment issue,
one could always include the field even if it were not processed, at the
expense of 4 or 8 bytes.

	The question of when to rekey really is independent of the counter
size, except in so far as it not being larger than the counter space.  So,
I'd tend to keep these concepts separate as much as possible.
