RE: Software for PKI
I see the ROI coming from the benefits associated with unified
authentication systems and ability to manage fewer disparate authentication
technologies.
I full heartedly agree about the continuous influx of drafts on solutions to
problems that are not well defined and even worse specifications that simply
do not map into any real business need :). I also see us continuously coming
up with new ways to do the same thing which is always fun :). I would
certainly advocate that we add a requirement that there is use case
documentation included with all of these technology drafts.

Where is the ROI over running a "hardened" computing environment with local
auth models?
The only thing that makes PKI of any real interest to many ifs that it
promises to take the "Human culpability" factor out of most long term
logging or instantaneous decision processes. But I to date have still failed
to see how its going to keep these promises.
This is the problems with allowing people to submit draft after draft on
technologies without require some rudimentary statement about how its to be
used and its constraints, which is why the TS Protocol, for example, is
still undergoing revision after revision.
Why not just mandate User Documents be required before anything is
transferred to a Standards Track? - BTW - take this as an official motion to
the WG as a whole for an amendment to the charter.
