Hi Hank,

you might want to be sure that you really need low-latency, rather than 
high-thruput. Also, do you need to be able to write to any node or can 
you live with a fixed gateway-node that all access is going through. 
Finally, looking at CAP and find out what two constraint are the more 
important to you. You might find that you could actually use Mnesia.
