There's been nothing mentioned about it on the zfs-discuss mailing list, and
I haven't seen it blogged about or mentioned in the changelogs for ZFSv14+,
so I don't think this has been implemented in ZFS yet.

I'm very interested to hear about your results with HAST/ZFS combo

I've only used it in testing via VirtualBox so far.  Our intended use is to
create a fail-over storage network (1 server at building A, 1 server at
building B, connected via gigabit fibre) for a virtualisation setup.  In
testing inside VirtualBox, it works nicely.  Just waiting for our fibre link
to go live to test it on real hardware.  :)
