Can we use smbmount+winbindd to mount user's NT home directory?

There is a PAM module called pam_mount that is designed for exactly this
kind of thing and its even GPL.  All we need to do is to rip the profile
location out of the login info reply, and feed this and the
username/password to smbmount.  I was intending to add this to winbind
at some stage.  (I've already discussed it with Tim, and he seemed to
like it).

In any case, the only sane way I can see to do this is:
 - PAM collects user's password
 - PAM mount's home dir (or ~/profile) as a session module
 - On logout, session is closed and home-dir umounted (if not busy).
