    Sorry this took me so long to respond to.  I am kind of swamped :).  I do like the idea of being able to access the version numbers for nimbus, but also for the supervisors.  This becomes especially important for HA and rolling upgrades of large clusters. It is good to be able to verify that all of the nodes are on the versions you expect them to be on.  I am OK with it being stored in ZK, so long as it is not written/read very frequently.
    
    Also if you think the configuration takes up too much room please take a look at https://github.com/apache/storm/pull/328 which makes the config paginated.

> 1) {nimbus.host} {nimbus.thrift.port} {storm.version} will be stored in  {storm.zookeeper.root}/nimbus like  "localhost:8826:0.9.3-r1234"
> 2) Storm Clients only need to configure {storm.zookeeper.root} to get Nimbus Server Information, Configuration like {nimbus.host} {nimbus.thrift.port} {storm.version} will be ignored
