This whole thread has been fascinating. I really wish we (OI) had
the two following things that freebsd supports:
1. HAST - provides a block-level driver that mirrors a local disk to
a network "disk" presenting the result as a block device using the
GEOM API.
This is called AVS in the Solaris world.
In general, these systems suffer from a fatal design flaw: the
authoritative view of the
data is not also responsible for the replication. In other words, you
can provide coherency
but not consistency. Both are required to provide a single view of the
data.
Can you expand on this?
2. CARP.
This exists as part of the OHAC project.

These are both freely available?
