Yeah I'm aware of the project and I wish the principles well as I'd like to see it succeed. ZFS is a lot different though than either lvm or a file system, which until ZFS and btrfs have been separate things. Along with RAID. Whereas ZFS (and btrfs) incorporate aspects of logical volume management and RAID, along with a file system. So it's not like they have to get a file system to work with underlying lvm, lvm to work with a file system. If there is a 3rd party solution that could work, Z-410 would be the one. But I still think storage management is something Apple should have done a long time ago. And while some think CoreStorage will be expanded down the road, I'm not so sure. ZFS and btrfs imply to me that the direction modern file systems are going in, is integrated lvm and RAID like capabilities, and COW instead of journaling. So it's possible CoreStorage is going to do only exactly what it's doing now which is a means to achieve full disk encryption (which has been achieved with dm-crypt and LVM for 7+ years on linux). Nevertheless a commercial 3rd party in charge of an on-disk file system seems like a challenging business model to make financially feasible.
