The 48 hours doesn't really matter if a consumer doesn't have visibility 
into the answer.  And anyway, in either case, you are seeking to hold 
and use the data for up to 53 weeks pursuant to the proposed market 
research exception.

I still do not understand why you cannot operate in-band or otherwise 
configure the user agent to send DNT:0 signals using your client-side 
software.  I'm sure there are engineering costs and challenges to all 
parties represented in the working group, but I had not heard before 
that responding to DNT:1 and DNT:0 signals would be technologically 
unfeasible (which would seemingly be more so for third parties without 
client-side software).

I also don't see how a conditional "C" signal helps.  Without 
definitive, machine-readable signals, it's hard to see how this system 
is accountable.  There is currently no general auditing requirement in 
the standard, and I would be reluctant to put one in as an unnecessary 
burden and expense.
