I have looked around for the ZFS API, but it appears like Sun hasn't 
released it; at least not into the wild.  Perhaps those in the 'Sun 
Developer' camp have access to such things.

If there is a defined relationship between Sun and samba, perhaps there 
is a contact that could put this on their todo list or pony up the 
needed information.

Meanwhile, I have submitted a request to Sun, but I wouldn't bet that 
would come of anything anytime soon.
