Just picking at one point...
According to some RFC:
"All relevant documents to be discussed at a session should be published
and available as Internet-Drafts at least two weeks before
a session starts."
If the above was followed there shouldn't be any draft submissions
during the week a meeting is held.
What about drafts that not for discussion at a session? What about drafts that
have completed last call or are in IESG processing?
Cheers,
Adrian
