I don't have an investment in either. 

AoE is a local storage network protocol: it can't be routed, but 
it can be the basis for cheap cluster storage. OCFS will run on 
it. If you can dedicate a switch or a VLAN to it, and separate 
interfaces on all relevant hardware, it's probably got pretty 
good performance over gig-e, even with no special hardware from 
Coraid. 

iSCSI is more complex. It goes over TCP/IP. It can be routed, it 
has authentication (but not encryption) and can be used over a 
VPN or IPsec. I see lots of people making money selling iSCSI 
products...
