Now would be a good time to decide whether you want to file an IAB
appeal or not.  There isn't much use in having the RFC editor do stuff
if we are just going to go into another 3-6 month delay.

I think it would be good to hear from the community at large on this
issue now and this can then be used by SPF Council when making a final
decision on it (...).

I already said I would abstain from the vote as a council member, but of 
course I do have an opinion on the "v=spf1 re-use" appeal:

I am still absolutely convinced that the appeal is technically justified.  
The Sender-ID spec sanctions the misinterpretation of already published 
v=spf1 records.  The owners of those records might find that their records 
cause unexpected loss of mail, which would not normally have been the case 
with a pure MAILFROM interpretation.  This might make them abandon their 
records or weaken them from "-all" to "?all".  And as Frank said, the IESG 
appeal was also useful to document our strict opposition against the abuse 
of v=spf1 records, even though the appeal didn't succeed.

Now the question is what an escalation of the appeal to the IAB could 
possibly benefit us.  The IAB cannot modify IESG decisions or make their 
own decisions, all they can do is _undo_ IESG decisions.  Since we have 
_not_ appealed to the IESG about their decision not to publish draft- 
schlitt-spf-classic as a "Proposed Standard", appealing to the IAB cannot 
turn draft-schlitt-spf-classic into a "Proposed Standard".  All an appeal 
to the IAB can achieve is to stop the Sender-ID spec from being published 
as-is as an "Experimental RFC".

Again, I think that would be technically justified.  But there are other 
issues we need to consider.  For one, appealing to the IAB could 
practically (if not formally) delay the publication of SPFv1 as an RFC 
even further.  Having a published RFC, and be it an "Experimental" one, 
would however be useful for convincing MTA authors and OS distros to 
finally include SPF support in their official distributions.  And having 
an "Experimental" RFC _soon_ could improve our position for claiming 
implementation and deployment experience when submitting SPFv2.1/v3 for 
"Proposed Standard" status in a year or so.

Besides, there are more solutions for overcoming the SPF/S-ID conflict than 
just trying to block the S-ID specs from gaining RFC status (which might 
not work at all in the first place).  Gladly, several people here think 
that creating a SPFv2.1/v3 would be useful.  In my opinion there's much 
more value in that than just any new features (such as new dkim, pgp, or 
smime mechanisms) -- it could make "spf2.0" and "v=spf1" obsolete in a 
year or two and thus resolve the conflict.  And it could be a better 
candidate for a "Proposed Standard" RFC than "draft-schlitt-spf-classic" 
was due to the conflict with S-ID.

It may be noteworthy, however, that escalating the appeal to the IAB 
wouldn't exactly stop us from proceeding with SPFv2.1/v3 now.  I think it 
would be helpful, though, to have an "Experimental" RFC soon to cleanly 
base the new SPF version on.

Now on to more specific comments:

I think we should proceed with an appeal, unless
1) the consensus is that there will be no more FUD to try and kill SPF
   (whether or not in the effort to promote some other protocol).
AND
2) the appeal has a reasonable chance for success
AND
3) the delay it entails is not deemed to have likelihood of being
   detrimental to SPF

To deal with FUD from MS (mostly), the obvious solution is to do better PR 
ourselves.  And of course I really don't have the slightest idea how the 
IAB people would judge the appeal, just like I didn't with the IESG 
people.

I believe that an appeal should go forward. My reasons are as follows:
[...]
3) SPF has everything to gain and SID has everything to lose by a
continued open and public debate. Conversely, SID has everything to
gain (regardless of the merits of the approach) at this point by
continuing to co-opt spf=v1 records without the SPF folks showing some
backbone. [...] Every additional spf=v1 record published is a draw for
SPF and SID. Every v2 record is a win for SID/MS. That is a recipe for an
SPF loss in the marketplace. [...]

I don't think we should conceive this as a race between SPF and Sender-ID.  
Those two are not mutually exclusive, at least not from a wider, more 
general POV.  I'd even go as far as saying that an SPFv2.1/v3 _should_ 
support the PRA in an _optional_ manner (that does not require implemen- 
tors to acquire an S-ID/PRA license in order to be compliant with the 
spec).  IOW, embrace and extend reversed.

Strongly disagree.  Having them on public record is already a very good
thing.  I've often used the URLs of the IESG appeals directory or of my
HTML version of Julian's mail in discussions. 

Without that it would be very difficult to fight Doug's verdict "SPF is
defunct because of the PRA re-use" (or similar). 

I absolutely agree with Frank's assessment regarding the appeal to the 
_IESG_.  As for another appeal to the IAB, see above.

When the first appeal occured, I was in favor of it. I think the word
"hindsight" captures exactly my current reservations for going down the
same path again. It was not wrong for us to try. [...]  I think that,
without 'material' changes in the field, expecting a different outcome,
just for the sake of it, probably will be a waste of time.

Just for the record, there _would_ be a material change: we would be 
appealing to the IAB, not to the IESG.  The very fact that the IAB can 
undo decisions of the IESG shows that the IAB is not their a puppet.
