I don't think HAMMER intends to implement a significant portion of ZFS's features. In particular, IIRC Matt specifically said he won't do anything about volume management (the data storage / RAID layer of ZFS) which among many other things means no ad-hoc file system creation. Also, HAMMER needs to be "vacuumed" periodically by design (the reason for this seems to me similar to that of pgsql) which isn't a particularly nice design.
