Re: [6lowpan] LLN roadmap documents: more missing pieces

Hi Michael, Don, and all,

>What Carsten said was that some kind of roadmap was necessary.
I agree with Mr.Carsten,

>I want to ask if it belongs in ROLL or 6lowpan.
IMHO, it belongs to 6lowpan WG first, and it MAY be for ROLL as well,
overall, I think the WG AD can give us the best feedback and suggestion.

if the protocol can work else than 6LoWPAN, then
IMHO we should let each group face its use-case problems,
not to give a protocol that works in many conditions to
only one WG or two. Each WG SHOULD look at its purpose case
for any particular protocol (as needed to be used is such area).

>the ZigBee Core Stack working group

I am looking for the group, but not found,
this group is not an IETF group yet !

I don't see the IETF has a cooperation with Zigbee standards. If I am
mistaken
please inform me, IMO we should not depend on the Zigbee-WG, until it
becomes IETF WG,

Therefore, the work you pointed to, should be considered by both 6LoWPAN
and ROLL.
