Because my first thread
"multiple user questions"
wasn't exactly verbalized by me and therefor mainly reads about the content server, I start this new tread (hopefully better targeted to the subject):

I have a Linux only LAN. I want to have two Libraries. To the first one all users should have access, while the second one should be only accessible by some of the user (say adult books).
And this is my idea how to get it working:
-setting up two new groups: ebook, ebook18
-users: child1, child2, parent1, parent2
-adding all users in the group ebook and only parent1, parent2 in the group ebook18
-placing the libraries on a nfs share, with the above mentioned grouprights
-preventing more than one instance of calibre running inside the network by starting calibre via a script, which does some ps and grep magic. So each client can start calibre or gets an error message like "library already occupied by user x on client y"

Only question to me is, if calibre gives rwx rights only to the user or although to the group of the user. Or if its somehow configurabe (even if I have to do it on the OS site via umask).
Or is python doing the rightmanagement completly different?

EDIT:
sorry, perhaps I was to imaptient (again) and the above mentioned post eventually gets me the right way.
/EDIT

EDIT2
ths first edit isn't exacly right, so i follow this idea, too
