Lars,
For what it's worth, I have the same question as Ben - if this guidance 
applies to the kinds of informal meetings in restaurants and bars that the 
IESG is encouraging, even if they aren't publicized and aren't open to the 
community, is there any way for two or more IETF participants to talk to 
each other, that's NOT under NOTE WELL?
I think it DOES make sense to say that the kinds of informal meetings the 
IESG is discouraging - in IETF meeting rooms, with agendas, mailing lists, 
presentations, attendee lists, and minutes - should include NOTE WELL 
notifications.
But if I was sitting next to Adam Roach on a plane headed for the IETF 
(which has happened before) when he was editor of GIN and I was chair of 
MARTINI (this last part did not), and we started talking about proposed 
changes to the GIN draft, is that covered?
Color me confused ...

-- Section 6 suggests side meetings should be (somehow "informally") 
covered by NOTE WELL. I think this is a very dangerous suggestion. The 
rest of the document suggests that a side meeting has no official 
standing. That seems to me to mean it's no different than a group of 
people who coincidentally participate in the IETF having a dinner or bar 
meeting on any subject at any time. Or a hallway conversation, for that 
matter. By the logic of this section, I can't really figure out how 
"informal" a meeting would need to be before it no longer fell under 
NOTE WELL.
In an informal meeting, the participants should be able to follow any 
IPR policy they like. I can even imagine an informal meeting covered by 
an NDA, where the participants want to decide if they want to have 
further discussions of a subject under IETSF IPR rules or not.
I think the best we can hope to do is suggest that side meeting 
organizers and participants be explicit with their expectations on IPR 
and confidentiality, so there is less chance for down-stream surprises. 
If we want something stronger than that, then we really need to create a 
new category of "official" meeting.
We actually ran this question past the IETF legal counsel before adding 
that section to the document. It was his stated opinion that the Note 
Well applies. I therefore don't see what we could do here.
Did the counsel describe the triggers that causes Note Well to apply in 
general? Because if it automatically applies to an unofficial side 
meeting, then it's hard for me to see where it _doesn't_ apply when 2 or 
more IETF participants have a conversation. For example:
