In this case I cannot see differences between local or aoe disks.
ZFS has the advantage (if we use it directly as filesystem, not ext3 on top of zvol) it can detect exaclty which file changed due to any kind of corruption (on disk surface, hdd bios bug, chipset bug, whatever bug). If you have redundancy (raid1, raid5, raid6 equivalent), it can fix this kind of issue and make the data redundant again. (There are a lot of benefits of ZFS, worth to ckeck.)
Thank you very much again!
Have a nice weekend!

As stated in my previous answer data corruption on the wire is ensured by the ethernet CRC32 checksumIf the corruption of data happens before the ethernet stack is reached on the wire nor iSCSI neither aoe can do something about that. Although I don't know ZFS, I guess in this case the data protection you're talking about should apply.

But don't take my word for it... keep on digging.
