(I figured this was worthwhile enough to fork off the raid enclosure thread)

I was disappointed to see the news as well, but it's clear something legal was likely preventing ZFS from moving into OS X. Not sure if Oracle complicated the situation, or what happened. I also wonder if this will impact FreeBSD in any way, as they have had ZFS support for a while now.

Apple at this point will likely try to build something similar in house, adding yet another file system to the mix, unfortunately.
