For the adventurous, there's Zevo [1] which is a port of ZFS to Mac OS X that supports all the fine grained details of the operating system: "ZEVO’s file system is fully integrated into the Mac’s unique OS environment and implements quotas, ACLs, and the HFS+ programming interfaces like search-fs, id lookups, bulk access calls and resource fork stream access." If I remember it correctly, the company is run by the guy that was responsible for the ZFS-Mac OS X integration at Apple that was canned shortly before 10.6 was released.
