If you did this, took a handful of machines, exported their storage
via iSCSI and had
a single server taking each of those iSCSI exported drives and
combining into a single
giant md device, would the theory of redundancy still hold?

Say, I had 4 devices with 500 GB drives exported using iSCSI.  If a
single larger server
took those four iSCSI export drives, and created one md RAID 5 device,
could a single
server be turned off, and just degrade the array until it was either
replaced entirely
or brought back online?
