    Yep. With one exception: Sun's gonna want to license that technology
to use it...but the idea _is_ very close.  We own the code...we can do
something like it.

    Yeah, but with a fob, they might write down the passphrase at home,
making it difficult to steal at work.  Even this provides an amount of
security not offered with current systems.

    Yeah, all the parts are there.  There's a daemon that'll watch and
take-actions based on USB insertions.  It shouldn't be a big deal. It's
not like we're inventing the wheel from scratch.

    And that's why I posted this here, not on Fedora-devel. I'm
interested in mobilizing a desire for the system, not interrupting a
bunch of guys working on other things to tackle another project. (Isn't
it amazing?  No one griped about that...)

    I've watched a lot of projects spring to life; the only thing
different about this one is that the parts are there, we just need to
glue'em together.  I think what we need most is a catchy name, then a
press release, and eventually some programmers.  :>  At least, that's
the way things like Samba, Sendmail, and Apache seemed to have come
about.  (J/K!)

    On the web-side, we could introduce something in the browser strings
that it normally sends the server.  Just add a key.  IIS and company can
barf on it, but if a browser is sending that key, it's because a fob has
been authenticated, and if a matching key is found, that user gets
logged in.

    This whole idea is made up of little things like that, which don't
appear to be a big deal.  I think the hardest thing is for Linux
programmers and well-wishers to be creative; to not wait for everyone in
the UN to sign on to the plan.

    Make this system, bang out the initial problems, and make it part of
the distro, and you'll see people everywhere picking it up.  Even the
legacy people.

    What can I do to help?
