Hello Terry,

This all seems fine and dandy, but there is a disconnect between what you say there "discussing a proposed definition" and "presenting a better formed definition to the IETF" (admirable intentions for a mailing list), and "determining an agreed IETF definition" as indicated by some of the participants on the list as well as in the revised mailing list announcement.

I hope I am not needlessly picking at words, but it seems that this disconnect could be the source of some future uncomfortable moments.

As Lou mentions, the topic seems to have avoided discussion on the TEAS list where it was invited to take place. That need not be a bad thing if the proponents need to self-organise a bit. And I see no harm in providing an archived mailing list under IETF "note well" terms for that self-organisation to take place. It's just about setting expectations of where the results of the organisation need to be taken.

Cheers,
Adrian
