so i think we're actually all on the same page. great =)

what i mean is that KPD should be able to not only provision passwords from
the user to the application, but also it (or an analog of it) should provide
a user interface as well as an API for application developers to easily
request credentials via hardware based systems (smartcard, fingerprint
scanner, whatever) ...

agreed. i was attempting to point people to the low hanging fruit that are
obvious and easy entry points from which we can start to talk about things in
concrete terms. e.g. patches. that is why i keep bringing up something that
is technically a trivial issue.

we've been there and done that already, just not with crypto but with
multimedia, hardware awareness, PIM data, etc. maybe we could learn something
from those lessons?
i'd also be cautious about falling into the "perfect solution" trap. this may
be a case where "incremental deployment", whilst imperfect along the way, has
the best chance of getting results (including a "perfect" solution) quicker
due to less friction (c.f. 90% of this thread) =)
