In general I'd disagree - but you've made an excellent point about innovation on PC being dead (and therefore no chance to properly secure them while keeping 'em usable). US DoD is moving along the "secure 'em" axis, thus making usability suffer (many reasons for that). Thus many bitching end-users (and some of them actually have reasons to). But overall - comparing what CAC were expected to do with what they actually do - I'd call it a success because they _work_, like it or not. (Now OS changes version and fragile middleware quits, some readers aren't supported, etc - overall not a pleasant picture, but the infrastructure is fine and the capabilities are right.)

various mailing lists such as:
http://www.opensc-project.org/opensc

Most of the people hanging out there are in some way working with the EU cards.

I guess you refer to PIV and CAC?
There is a fundamental difference between the US and the EU and that
only in the EU there is something called "citizen-cards" or eID.

Citizens are supposed to buy eID for carrying out secure services on
the Internet.  The cost have been high; results have been marginal
for the reasons I listed (and some more...).

Obama's NSTIC is something similar (but still very different) that
will be slightly interesting following although I don't think
their NIST friends really understand the consumer market and
the huge technical issues they will have to deal with.

IMO, the PC platform is dead as a vehicle for innovation; they
might go to phones from the start.  I never understood why
you need a picture on a token for Internet access :-)

Well, "it has always been like that" is probably the [lame] excuse.

Anders
