I don't know but I did hear from Coraid about packet corruption and they
convinced me (for now) that the Ethernet level of error detection should
be sufficient.

I am.

Yes. I have two machines running against two Coraid SATA/RAID units.
One machine is all production. The other is experimentation and does
data backup to the second Coraid box.

I don't know. It seems odd to me to talk about *booting* from AoE.
What BIOS supports that? OTOH, booting from the network and then using
AoE for root seems simple enough.

I've only used Xen with AoE. It's an integral part of the way I want
to use Xen. Moving domains between machines should be trivial and
setup is incredibly easy (especially compared to iSCSI, etc.). And,
of course, it's handy to be able to pick up 7TB+ chunks for cheap.
