Hi Pekka,

We will fix all edits below.  Thank you for this extensive review of our
spec.
All your input below is valid.

Thank You,

The operational issue the user has to consider for IPv6 packets in their
network is they are now only fragmented e2e, if at all, and this can
affect an enterprise like a discrete engineering operation that sends
MBs of data modeling across the network or a financial institution bulk
wire transfer updates, etc etc.  PMTUD is important to be used.  I think
PMTUD is the correct word and later needs more discussion in the follow
on text.  What other word would be better, to point out this in a
listing of bullets?

Agreed.  WHen I keyed this in as editor I knew someone would ding us on
this one for sure.  The idea is to get some crisp bullets of where the
core trust beliefs can be shattered in the minds of the users defining
how to adopt IPv6.  Some of the ones I hear, as a note, are fallacy and
not reality, and some are completely missing.  But yes this needs major
wordsmithing.

We can fix that yes.

I will look at this as editor.  I followed templates/current-wisdom the
IETF points me to as a note though.

Hmmmm.  NROFF did it correct it got munged by peoples mailers on the

ACK.

Not necessarily esp. multi-site enterprise.  Will reword.

That fixes the issue above too.  Thanks.

I agree. I think we were practicing valuing differences :--)
