Seems pretty useful once all the drivers, utilities, network devices catch up. This will be all the rage in SAN and other performance network environments in a couple years. Would be great to see a more thorough performance evaluation. For example I wonder if the throughput and latency hold in different network conditions - e.g. network conditions with high latency, packet loss, and both. I presume after a certain point of degradation the larger packet size becomes of penalty because your retransmissions become very wasteful.
