Thanks,
	I was playing around with zrep, but out of the box its a little limited
in that it gets confused if a new zfs volume gets created. If that
happens, you have to start from scratch. Also need to hack it to work
via netcat instead of ssh (boxes are 10G xover cable).  I like the idea
of zfs syncs, but was hoping to avoid rolling my own version of zrep.

Thanks for the threads, they for sure list some of the caveats of HAST
and why I am not a big fan of it either.  I too am leary of automatic
failovers in this case.
