hi havard,

> a tangential remark related to the wording in the draft:

i would not call actually talking about the draft's wording to
tangential. :)

>>    The length of the Interface Identifier in Stateless Address
>>    Autoconfiguration [RFC4862] is a parameter; its length SHOULD be
>>    sufficient for effective randomization for privacy reasons.  For

thanks for actually suggesting useful text.  beat us up if something
reasonable addressing this is in not the next version.
