Folks,
I think we are at the point where a fresh draft would be helpful.
Agreed. I think we're pretty close to something viable here.
Coincidentally, I finished the draft today and planned to submit it
tomorrow (it's evening here), but couldn't resist submitting it now
after seeing these comments.
Since I couldn't get the submission tool to identify the author's
information (god knows why - is there a new rule that I-D's cannot
have 3 authors perhaps?), I had to request manual posting. It should
appear in the directories within the next 2 work days.
Meanwhile, the document is available from:
http://www.welzl.at/research/tools/email/draft-welzl-expires-00.txt
Now go ahead and tear it to pieces :-)
Cheers,
Michael
