He didn't mention about roles. I have a similar implementation on my
website and let me explain the point I had, and would want Alexander to
point out if this is what he wants.
Consider he assigns the following
Scene1
----------------
User2  a,c,d
-User3 a,c
-User4 c,d
-User5 a,d
-User6 c,d
-User7 d
----------------

If c is dropped from User2, it should look like
Scene2
----------------
User2  a,d
-User3 a
-User4 d
-User5 a,d
-User6 d
-User7 d
----------------

Now if c is added back to User2, he wants to get Scene1 again. Would
this not mean that there should be some kind of storage which as follows

User2 c
User3 c
User4 c
User5 -
User6 c
User7 -
Such that on giving c to User2 would give the permissions as above to
others.
I say this approach because what if Scene 2 is changed as follows at
some stage

Scene3
-----------------
User2  a,d
-User3 a
-User4 
-User5 a,d
-User6 a
-User7 d
-----------------

Now if we put back c to User2 don't we want User3, User4 and User6 to
get c normally - but now we won't be back to Scene1.

I would expect Alexander's input, to check if I am pointing in the right
direction.

Aman
