Wojciech,

Thanks for your answer.  I was wondering what the current
state of opinion was for using soft-updates on top of a
geli provider.  From what I've read, disk write caching
reduces the effectiveness of soft-updates.  I was curious
if geli with authentication would obsolete soft-updates
or not.  I may be mis-understanding soft-updates.

Does that mean you are/aren't or have/haven't run
ZFS on top of, say, 3 geli encrypted disks?  I'm curious
as to whether there are many people who have tried it,
and use it.
