Thanks Daniel and Hendrik, Since it has been a some time when we
discussed about this draft, here is a summary of discussions that we
had on this draft regarding the adoption:

Brockhaus, Hendrik:
>Thanks to Mohit for his request on rechartering and adoption. I support this.

Panos Kampanakis:
> I oppose adoption unless there is a compelling reason why. Also I am not sure where this draft would be implemented and used. If this is just for one or two vendors I don’t think ACE needs to spend the cycles.

Brockhaus, Hendrik:
>I think we have to accept that there are different protocols with different abilities chosen in different verticals.

Michael Richardson:
> I have no fundamental objection to this work, and I think that it should be adopted.
>But, I think that it is worth doing more than just s/http/coap/.
Plus some suggestions on the draft.

Mohit Sahni:
> Some of your suggestions should be discussed in the context of the LightWeight CMP profile draft
> I will work on making it more clear what are the pros and cons of using a proxy vs direct communication
> I will add the endpoint definitions and make resource discovery more clear in the draft.
> This draft only defines how to use the CoAP transport for carrying the CMP messages. When and what CMP messages are sent should come under the CMP protocol implementation itself

Olaf Bergmann:
> One thing that might get in our way when doing this in ACE is the emerging input for draft-ietf-lamps-lightweight-cmp-profile. But otherwise, I do not see a strong reason for not adopting draft-msahni-ace-cmpv2-coap-transport.

Brockhaus, Hendrik:
> Actually this was first discussed in LAMPS, but as the draft focusses on CoAP transport and not on CMP specifics, the group had the opinion that ACE is the better home as here is the knowledge regarding CoAP.

Thanks
Mohit
