No POSIX acl support let alone NFSv4 ACL support. The sole reason why I
have not yet gone Linux samba frontends and OpenSolaris ZFS backends
glued together with Gluster. It does support POSIX permissions but that
is not specific enough nor close enough to the NTFS security.
Other than that, I would have given GlusterFS a go a long time ago.

Define cheap. Like these...er...hmm...creative chums here?

Or how about 7850USD for a 4U, 36 bay ( loaded with 12 x 1TB - not going
full out :-( ), multipathing dual SAS host controller + sas backplane, 4
port GB Intel NIC + dual GB Intel NIC, 16GB ECC DDR2 RAM, multiple HT3
links, dual 6 core cpu box? Future 45 bay 4U SAS storage box possible too.
No, not putting Centos 5 on that. :-( Not trusting raid5/6.
raidz2/raidz3 it is going to be.
