There are actually quite a few really good resources and good walk-throughs out there. There are a few things that really none of them talk about on any real level and that is what *should* be used or in which way it should be used. First off NFS does work with OS X Leopard and using the directory utility under the utilities folder in applications can be setup to automount. But NFS seemed really a pain to deal with and doesn't offer similar level of general functionality as AFP does.
