The login(1) program currently does this to some degree.  While
the authentication has been PAMified, it looks to me like a lot
more needs to be moved out into PAM account and session modules.  
The simplest would be to stick it all in pam_unix, or it could be
broken down into finer grained modules.

Does anyone already have plans for this?

Thin it should be easy to hook xdm into this.  I would assume
that the Linux crowd already have some XDM patches kicking around
for PAM....
