indeed, such a capability would go far in forcing accountability to the
self-reg regime that predominates the online playing field in the u.s. 
the ftc does not want to regulate and companies don't want to be
regulated, but there continues to be pushback that industry
self-regulation is inadequate because it is still largely opaque and is
being gamed by many of the entities who benefit from the information
asymmetries. 

implementation of a subject access api would put teeth behind the recent
'pledge':

i'd suggest the challenge is a hybrid of the above, ie., knowing the
capabilities (the frequency, occurrence AND demographics of the entities
that storehouse MAC addys) and social expectations of their USES as it
relates to causing injury/damage/harm from a legal perspective.    so,
for example, people are more concerned about IPA as a secondary
identifier/digital fingerprint because it's often the principal
evidentiary underpinning in affidavits for search warrants or subpoenas
relied upon by private IP owners (e.g., RIAA, John Doe lawsuits) and
gov't investigators.  so, there's a normative expectation of privacy in
that network artifact that hasn't attached to mac addy's because of how
IPA is being used to impact people negatively.  i think it's just a
matter of time before we get there w/ mac addys. 

perhaps it's helpful to analogize to expectations associated with dna:
there was little concern about dna expectation of privacy when our best
methods to identify people were based on a/b/o blood group typing ...
that changed as pcr or rflp technology enabled that same blood spatter
evidence to distinguish individuals to the exclusion of others by
anchoring off of the dna in blood.

given that diatribe, that's not to say that our laws don't have some
evolving to do w/ respect to interpreting privacy harms, but people
don't take notice until they suffer tangible harm.
