ZFS has got a future? Where? Oracle is the initiator of brtfs, so where do you see a future for ZFS? Where do you see a future for Solaris? Oracle is a major contributor to Linux, why should they support any further development in this UNIX-incarnation?

That said, I'm an avid user of ZFS and I'm looking really forward to its development. But I have a very bad feeling about it.
