Yes we currently have BMR setup in the lab, and are doing some testing
right now.....as a matter of fact, a win2k3 server is rebooting as I
type this.....definately seems easier, to a point.
BMR still can't restore SDS mirrored disks the way they were
originally.....you end up with one disk and have to rebuild the
metadisks.....but it's a lot easier than building the machine to start,
restoring, breaking metadisks to get the restored disk to boot, then
repairing the metadisks.

Yeah, I'd definitely be interested in seeing this case you have
documented.
You can post it to the list, or send directly to me.
