This is a re-review of this document.  The document incorporates some
of my suggestions from the previous round.

There has been no change in this area.  Do the authors feel that the
additional reference to "Security Threats to NETLMM" is not necessary?

This is also unchanged.  It would be useful to clarify if the HA is a
Home Agent, Home AAA Server, etc.

This has not been fixed.  After further investigation, it seems that
these mean "Diameter EAP Request" and "Diameter EAP Answer" as defined
in RFC 4072.  Although the acronyms are defined in a normative
reference, and may be obvious to readers already knowledgeable about
the subject, please consider expanding them in this document at least

This appears to have been fixed.

This appears to have been fixed.
