Well, James, why not 100MbE? If you want a comparison of target 
implementations you need a fast hardware with minimal latency. 
Otherwise, the difference between the implementations can drown in the 
overhead of the accompanying processing. 1GbE is a nearly 10 years ago 
interface. Or are we going to stay ten years behind progress?

Thanks,
Vlad
