Least i think so anyway, i prepare myself to stand corrected :)

What i'm certainly trying to say is that i don't think you need to worry
about it since the server aspect of file and printer sharing (or samba)
should handle it for you.

You've kind of hit the nail there.

SMB doesn't really deal with filesystem permissions (NTFS on Windows or 
ext2/3/reiser/whatever on Linux).  It will send "authentication data" to higher 
level protocols (Windows filesystem stack, or Linux's filesystem stack) to determine 
whether a user has permission to read/write any particular directory/file, but SMB 
itself doesn't support complex permissions.

The way one of my Microsoft instructors explained it to me was that permission to a 
given remote file is like going through 2 separate gates.  One gate is called SMB 
and the other gate is called FS.  If a user has permission to go through both gates 
then they will be able to perform actions on the remote file.  Neither gate, 
however, determines the other gate's permissions.

Now, I hope that makes sense written down because I've just re-read it and it looks 
like random rantings to me :D
