Yep.  I was just describing the experience that OS X went through in =
implementing extattrs / legacy resource fork support.  To recap it very =
briefly:  Having NFSv4 support extattrs (or even named streams, if you =
want to go that far) is the comparatively easy part.  It=92s backing =
them up / copying them around that gets more involved, and if you can=92t =
back up certain attributes then you=92re not likely to get anyone to =
want to use them, at which point the whole =93sharing=94 aspect kind of =
takes a back seat.
