Letting users modify there own 'valid users = ' directive

[The Hermit Hacker]

Here's an odd question/request ...

Right now, if you setup smb.conf with a [homes] section, anyone can
connect and login to the server, as themselves, and mount their home
directory.  No probs there.

Has anyone thought of, and possibly implemented, a means where that end
user could change things for themselves to extend permissions on their
directory?  

Basically, make a Win based utility that would connect to the smb server
(smbd would most likely have to be extended for this) and allow a user to
modify how their [homes] share is accessed.

For instance, Joe-blow user wants Jane to be able to access, modify and
work in his directory.  By default, [homes] only allows him to access it,
so he runs this config utility that adds a [joe-blow] entry to smb.conf
that contains the same/similar info to [homes], but adds:

force user = joe-blow
valid users = joe-blow, jane

To the new entry.

Something like this could be further extended so that when the config
program is run, joe-blow would be presented with a list of all shares on
the system where 'force user = joe-blow', allowing him to change the
'valid users = ' entry for each of them...

Reason for asking:  Over the past year, I've been working on getting our
Novell group to accept moving all the WWW accounts for all the students,
staff, faculty and departments over to a Unix host with Samba.  This
"permissions" thing tends to be my one major hurdle on this, since, under
Novell, users do have this ability...

One suggestion that I've heard was to write a Java server for the Unix
side of things, and then Java clients for the Windows, where the Java
server handled locking and modifications ... 

Anyone?
