lofiadm is used on Opensolaris so you can use it in Openindiana.

Would like to know what performance you are getting from lofi
as compared to other solutions mentioned.

UFS in the zvol container on ZFS:

Using file instead of zvol (I think Zvol is better instead):

And why using block encryption:

I imagine zfs send to such zpool inside lofi zvol will do it. (lofi does 
not do compression I think).
