Ok, so you get the multi-level, compression, encryption, error checking, and RAIDZs? Anything else significant I am forgetting? Can ZFS take an iSCSI block device as a pool member? (Did I use pool right there? Like and LVM volume group, right?) If so, risk of infinite recursion asside, that could be a very powerful way to leverage a local FusionIO device to buffer an iSCSI storage cloud/SAN.
