Harry,

I fear you have misunderstood the problem. *NO* such agreement is needed
for FIDO, whereas no such agreement can be *made* with GP precisely because
members are allowed to hold onto patents crucial to GP without licensing
them.

So unless/until you can get every GP member to join such a hypothetical WG
(which again, I do not believe should be WebCrypto), then it would be
knowingly standardizing an encumbered technology. Surely you and your
colleagues at the W3C can see the fundamental danger in this.

To be abundantly clear: I consider the Gemalto solution as unimplementable
as is, *independent* of the GP issues. But the fact that there ARE GP
issues, and not disclosed, is equally troubling.

It would be mistake to call the Gemalto solution mature when compared with
FIDO. It is architecturally similar in flaws to the PayGate proposals of
the past.

To be explicit; I disagree with the premise that it is a good or worthwhile
goal to expose these tokens. That sets an unquestionably wrong set of
priorities - that is, it assumes we must, and thus we will shove any
solution that fits "close enough" into there. The question is not "How do
we", it is "How could we" - a question that recognizes that the answer may
be "We can't", or that more changes are needed than just at the W3C level.

This is a fundamentally flawed process. The proposal put forth ignores much
of the conversation had for _years_ during our past meetings and on the
list, and yet is proposed as new and novel. It's not. There are enough
fundamental, architectural issues that it really is incumbant upon the
proposers to re-evaluate the approach, rather than suggest that unless
members assiduously and meticulously tear apart *and rebuild* the solution,
that it's somehow the best.

No, we have at least one concrete proposal that is far more mature with
respect to privacy - FIDO - and the security considerations should serve as
a baseline for any counter-proposals. A proposal that actively ignores or
attempts to dismiss these considerations absolutely deserves to be on the
pile of "throw proposal away."
