    4. That what is being ported to Mac ... in 10.5 Server was supported and suddenly without a word he was eliminated in the 10.6, so I rather doubt that Apple is interested in ZFS, surely will be preparing their own.

    5. And Oracle is in charge of the two. I'm surprised that has not tried to link the two developments.

    Regarding Mac The truth is that there was much talk that zfs replace hfs +, but decided to stop it. Zfs was not really designed for the desktop, but hfs + would have been rather an update.
