Ballot question: "Is this charter ready for external review?"

Alvaro Retana (was Block) No Objection

(Alissa Cooper; former steering group member) (was Block) Yes

Updated text is much improved, thanks.

(Ben Campbell; former steering group member) (was Block) Yes

Thanks for the updated version. I think this one is better.

(Spencer Dawkins; former steering group member) (was Block) Yes

Thanks for the significant rework resulting in 00-02. I'm happy to ballot Yes on the result.

The following might not have been clear in my previous BLOCK on 00-01, so let me try again :-)

As the responsible AD for DTN, I am very interested in any thoughts the IPWAVE community has about the suitability of DTN's chartered work in the IPWAVE space, and welcome that conversation. My concern in my previous BLOCK was that the IPWAVE community might have already looked at DTN's chartered work and found it unsuited for deployments that will be based on IPWAVE. If that's happened, I'd love to hear more. If it hasn't happened, my apologies for misunderstanding.

(Stephen Farrell; former steering group member) Yes

I think the charter ought also recognise the privacy sensitivity of 
potentially tracking people and their vehicles. So I'd suggest 
adding something like: 

"The WG will pay particular attention to the privacy characteristics
of protocols it develops (or re-uses) in order to as far as possible
ensure that IP in vehicles does not offer unwanted tracking 
opportunities."

To forward the feedback I sent previously:

"Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I, not to be mistaken with V2Internet) communications are still being developed."
I read the charter multiple times, and I'm still not sure what the infrastructure is in V2I.
A sentence or two with background would be useful.

"Other SDOs interested in this work include ISO/TC204, ETSI TC ITS, 3GPP, and NHTSA."
Sure, it's interesting to know but what is the message for the ipwave group? Liaison, coordination, something else?

Supportive of the work though as others mentioned, the
description is quite vague. Agree with Alvaro, prefer future
work not to be mentioned at this time as seems more
appropriate for routing.

The first paragraph was difficult to parse as appropriate
for a charter (too commercial), the second paragraph
seems to be a better start.

From the first paragraph, "safety applications using
bidirectional data flows" seems to fit better with the
later text on safety-related messages to describe
what is needed.

I'm very supportive of this work, but do also agree with Mirja et al on vagueness of the group's work and scope.

(Kathleen Moriarty; former steering group member) No Objection

I agree with Benoit and Mirja, I had to read the charter a few times to get an idea of what this group might work on, but the milestones seem like high-level goals, so I think that is okay.  From the text, the development of a protocol is not clear to me and I think it's because of the following two sentences:

However, IPv6 on 802.11-OCB is not yet defined.

The group will work only on IPv6 solutions.

Then, you see that development of a draft for IPv6 on 802.11-OCB is a milestone.  Could this be made more clear in the charter text?

(Mirja Kühlewind; former steering group member) No Objection

To be honest, to me it's more clear  from the charter what the wg will not do than what the will do, however that's okay.

One question though: the charter says

"This group will develop IP-based protocols...".

Is it right to use the plural here? Will they work on multipe protocols or just one?
