Frankly, vlad, I think the new OS X is heading in the same direction as XP, just not as fast. At least in OS 9, the user has full control of the computer (Someone asked, "You mean you can just DELETE Internet Explorer??), the interface and file hierarchy so transparent, that there is no way a file such as this could hide. Even if the developer turned it into an invisible file, various search programs show such files and they can be made visible again. There is no such thing as a file you cannot delete on a Mac unless it is being used at the time.
