I'd like to be able to take nfs out of the equation but the limitation 
which cifs imposes on file ownership is too bad.

Are you saying that I can use cifs in place of nfs for Linux clients? 
E.g. their home directories? I want files there to be user:group 
-rw-r--r-- cifs lets me do it for one user only. THat's no god in a 
mutiuser domain.

If I have a share mounted using cifs, I can specify a uid and a gid of a 
user. If another user logs in, how do I then tell cifs that the uid:gid 
has changed without getting root to remount the share for me?

I've tried with autofs. Is there a way to pass the uid:gid to the 
automounter so that it is mounted correctly?
