I'm not doing anything yet; I just wondered if ZFS provides any methods to do file level cloning instead of complete file systems. Basically I want a zero-size-increase copy of a file. A while ago BTRFS developers added this feature to the fs by doing a specialized ioctl call. Maybe this isn't needed at all since vmware can clone but I have the gut feeling that doing this at zfs level is more efficient. I might me wrong though.
