The next version of MacOS X, Leopard (a/k/a 10.5) has been rumored  
for some time to contain support for ZFS.

I've seen some "clarification" that ZFS support in Leopard will be  
"read-only", at least initially, i.e. it will be able to read a ZFS  
filesystem if it's attached to a Mac, but it won't be able to write  
to it nor boot from it.

However, I've seen more recent rumors that at least some developers  
have been seeded with full read/write versions of ZFS on some Leopard  
betas--though I don't think any of those support ZFS as a boot  
filesystem.

Nevertheless, might full (non-boot) support for ZFS appear in Leopard  
in the not-to-distant future?  Perhaps for the server version of  
MacOS X?  Matched with an upgraded XServe RAID that might not be a  
bad lower-cost NAS/NFS server implementation, with, I now see, NetApp  
like snapshots.
