we are going to do this with kenfs and aoe.  our main filesystem is going to look
something like

	cm0f{(m1m2m3)e99.0e100.1}

where e99.0 will be a local shelf and 100.1 will be remote.  there is no compression,
but only changed blocks are dumped and kenfs doesn't really care how long the
dump takes.
