	We had a brief related discussion about this the other day and the
general feeling was:

  * Most applications using PAM assume that authentication is done by 
    username and password

  * There may be some support out there for smartcard type 
    authentication in applications but its certainly not implemented 

  * Things get complicated with a challenge-response authentication 
    scheme which some card based authentication schemes are based on - 
    think about things like one time passwords generated using a 
    challenge from the server. Most applications don't have support for 
    such schemes

	I had a recollection that someone had worked on smartcard
authentication support in gdm before but a brief look at GDM isn't
showing me anything obvious.
