I'll be looking at these 2 technologies in more detail (currently i've
played with AoE, dead easy to setup!). I'll do my best to document my
findings with regards to speed, will be interesting to see the difference.

But, they do solve different problems, the fact that iSCSI is routable
means that it's deployable in situations where AoE isn't (without layer
2 tunneling magic).

So, I'll mail back with my findings, hopefully it will help some.
