Very exciting stuff indeed, as I read through the documentation and 
watched the demos on http://www.opensolaris.org/os/community/zfs/ I 
become curious how you are going to implement the NFSv4 like ACL scheme?
Also I am a bit confused in how deeply you planned to use ZFS.
Is this like only root in UFS and the rest in ZFS? How about swap?
