Can GDM allow passwordless logins for specified users, in Ubuntu?

Agree mostly Khad - I don't feel happy with the idea of removing 
passwords from users given the approach Ubuntu has chosen.  It would be 
much better to find a way of keeping user's passwords, but just have GDM 
not ask for them for certain users if logging on locally. Just like KDM 
can be configured to behave.
