I have reviewed this document as part of the security directorate's
ongoing effort to review all IETF documents being processed by the
IESG. Document editors and WG chairs should treat
these comments just like any other last call comments

As you might guess from the draft name, this is an informational
document describing a number of use cases for low-power wireless
personal area networks. The security considerations section,
reasonably enough, briefly indicates why different use cases may have
considerably different security requirements and what some types of
such security requirements could be.

The thing that I think is lacking is some hint as to where to look to
find possible mechanisms to meet those requirements. For this type of
document, no detailed analysis of mechanisms is needed. But I would
feel better if a sentence could be added such as follow (with some
alternative wording in square brackets): "These varied security
requirement [can commonly][are expected to] be met by the use of
mechanisms such as IPsec and IKE, TLS, or 802.15.4 link security.". If
there is an appropriate security mechanism survey document that would
be fine. I did look at RFC 4919 as something that could be referenced
and it seems too preliminary and tentative. RFC 4944 is only a little
better. Perhaps there should be a reference to
draft-qiu-6lowpan-secure-router at least as an example of work in
progress in this area.
