cards and tokens are a proxy for the use of a certificate authentication
system...

You can in fact do certificate auth without the use of cards or tokens
or mix and match physical tokens and other private key storage depending
on need with the same authentication backend (typically ldap).

Since this plays nicely with eap-tls, 802.1x. ike, ssl/tls, and s/mime
it seems like a shoe-in, once you have a uniform authentication system
one is inclined to use it for everything. obviously being involved in
several of these with with multiple ca's is something of a pain in the
ass if it involves juggling 2 or more tokens instead of passwords.
(which are already a problem if you have to trach quite a few
non-overlapping ones.

Typically tokens continue to require passwords or some other method to
unlock them for use, effectively making them two factor (secret+physical
possession)

Are any network providers supporting smartcards or other non-password

for choosing/not remembering good passwords instead of blaming the
technology for choosing/not doing things so the user isn't forced to
work around its flaws.

I know about the DOD Common Access Card.  One-time code-generator tokens
seem more widely used by single enterprises.  But inter-operable
credentials still seem to be one of those great unsolved problems for
compter security.  Are passwords still the only lowest-common-denominator?
