With OpenSolaris and ZFS you have a chance to get closer to
what you want, using the NFSv4 ACL model. But right now what
you want (100% NTFS ACLs usable from Windows, local Unix
processes and NFS) is just not possible. Even large NAS
servers like the ones from NetApp and EMC don't give you
that. This is just not solvable 100%, because Windows, Posix
and NFSv4 have different ACL semantics.

With NFSv4 ACLs available in OpenSolaris and ZFS you get
very close, and we will be happy to help you utilizing
