NFS in 5.x has the same or better consistency guarantees as your favorite 4.x version. And in 5.5, you get NFS Version 3 and NFS over TCP, which work so well and so fast I was amazed when I started here. You're clearly out in left field on this topic. I won't argue about the ills of a larger memory footprint, other than to comment that 5.5 is much better in that area.
