Completely agree with Al. If anyone really wants access to forks they can implement them via the xattr interface (ok it has the 64k limitation but most forks are quite small so not much of an issue). That's how I implemented access to named streams in Tuxera NTFS and it works a treat (and allows Linux apps and various security modules that require xattr support to work properly which is also great).
