I'd stay away from AoE for high availability, I've tried it at home but performance can fluctuate and the AoE driver present in CentOS 5 is way too old. I wasn't able to build a HA setup without corrupting data when failover occured. For what I'm using AoE - to boot my mediacenter - exporting a single LVM LV, it works perfectly fine for me. For more serious uses, iSCSI is definitely the way to go.
