Oracle and SUN When it comes to dealing with storage, Solaris 10 provides admins with more choices than any other operating system. Right out of the box, it offers two filesystems, two volume managers, an iscsi target and initiator, and, naturally, an NFS server. Add a couple of Sun packages and you have volume replication, a cluster filesystem, and a hierarchical storage manager. Trust your data to the still-in-development features found in OpenSolaris, and you can have a fibre channel target and an in-kernel CIFS server, among other things. True, some of these features can be found in any enterprise-ready UNIX OS. But Solaris 10 integrates all of them into one well-tested package.

"Remember, though, that this is just one developer's aesthetic opinion."
It's not just one developer aesthetic opinion. Layered design is superior to monolithic design.

My interpretation of the original comments were that they were about the customary layering of subsystems in the kernel, which is not something that users see or care about. In other words, I think that he meant that "ZFS does not map directly onto the storage management architecture in the linux kernel and thus would be a pain to implement in linux" and just said it in a sensationalistic way.

ZFS is good, but layered ZFS would be better, for many reasons. Can ZFS do reiserfs over LVM over RAID over NFS, SMB and gmailfs?

Yes! There is no rule saying that ZFS cannot be used over a traditional volume manager, on a loopback file (over NFS), or that a zvol cannot be formatted with a traditional filesystem like UFS. It is just not common.
