I don't think it's a realistic view. I think AoE missed its window of 
opportunity and is now dying. As Tracy said, it's ridiculously easy to 
setup an iSCSI system. It's a pain to get the AoE target up to date in 
any distro, and the initiator, while working, is far from being a well 
behaving component.

I was never able to push AoE anywhere beside my projects. Blame me if 
you want, but most of the time free iSCSI was the obvious, variously 
documented, community supported, distro included, choice.
