 Putting this online is one of the main things I will be able to do
 along this path over the next week.

 Well, it may not be necessary to reinvent it. We'll see. Are there
 requirements for an infinispan protocol documented anywhere?

 I did this originally, however, I moved to a server side message
 routing for a few reasons.

 - It is easier to coordinate the smaller number of servers when a new
   one comes online, or goes offline.

 - It allows fewer connections per server, client side routing requires
   that each client connect to each server. For our scale, thousands of
   servers, this is an issue.

 - It guarantees a consistent mapping of data to servers for potentially
   disperate clients.

 - It makes the client side code easier to write.


 That said, if the client does do the hashing, the server will still
 do it, and make sure that the data arrives at the correct server. So
 nothing prevents the client from doing the hashing.
