It defaults to changing all occurrences, with an option to change it only in the current view. Huh? mv(1) is userland; whatever it does, by definition it boils down to a sequence of system calls. If those "views" of yours are pasted together subtrees of the global forest, you already can do all of that with namespaces; if they are not, you get all kinds of interesting questions about coherency. Which one it is? Before anyone can discuss possible implementations and relative merits thereof, you need to define the semantics of what you want to implement... And frankly, if you are thinking in terms of userland programs (file manglers, etc.) you are going the wrong way - description will have to be on the syscall level.
