Subject: Conflicting experiments

Hi, that's probably a stupid question, sorry.  The drafts...

draft-schlitt-spf-classic-00.txt
draft-lyon-senderid-core-00.txt

...have been both sent to "dea-dir".  I've no idea who this
is.  They document different experiments (SPF and Sender-ID).

The second experiment would corrupt the first experiment by 
(ab)using the same data.  It offers a way to opt-out of the
second experiment, but the about 750,000 participants [1]
of the first experiment don't all know this, the second
experiment was started almost a year after the first.

As a result mails will be handled as "spam", which are in 
fact no spam.  All that has to be done to split these
experiments is to remove chapter 3.4 from the second text,
i.e. draft-lyon-senderid-core-00.txt

This was also some kind of "rough consensus" of the former
MARID WG [2], the dubious chapter 3.4 is a later addition
by the authors of the secod draft.

Maybe the coauthor M. Wong of both drafts could help to
clarify this confusion.
                           Bye, Frank

[1] 750,000 is a claim by an early adopter of the 2nd draft
[2] "rough consensus" as identified by the former WG chairs
