Re: [lamps] Support for working on the lightweight CMP profile

[Tomas Gustavsson <[e-mail]>]

Hi Russ,

Is this question directed to the people who expressed support for the
profile?

If so:

> 1) If this work is added to the charter, will you contribute to the
> document?

As in writing the actual text of the draft, possibly, but not planned.

> 2) If this work is added to the charter, will you review to the document?

Yes. I have reviewed the suggested draft already and given feedback. And
will continue to do so.

> 3) If this document is published as an RFC, will you implement it?

Yes. Our software acts as CMP server in many industrial use-cases and we
implement several CMP use cases (among them the 3GPP CMP profile).
Therefore we will most likely support the new profile as well.

Regards,
Tomas
