Contrast this with POSIX/Linux, where every file has to have exactly one owner; even if they create that file in a shared directory, it still gives the creating user a special status over that file, that others with write access to the containing directory do not have.
(Multics also offers a separate “append” permission, that allows the possessor to create an item in a directory, without having the ability to remove an item once it’s there.)
Looks like this sort of ability may come to Linux after all <http://lwn.net/Articles/661357/> ...
