Ok I think I understand what you are saying.  If an item is shared 
read-only, it will always be read-only no matter what collection it is 
in because that ticket (perms really) will be attached to that item.  
But the problem I see with that is an item can be shared both read-only 
and read-write so how are we going to determine which permission to use?
