Right now, the task of keeping track of what servers are in a cluster
and what data they have is pushed off to the user.
Zookeeper would keep track of that (and would also serve as a single
point of configuration).

Wouldn't it be nice to be able to start up another server like so:
java -jar start.jar -Dcluster_id=foo

And just have everything work (no updating loadbalancer configuration,
other clients, etc).

Then there is master failover - a somewhat harder problem... or very
much harder, depending on how one approaches it.
