Hi, Mahadev said it all, we have been thinking about it for a while,  
but haven't had time to work on it. I also don't think we have a jira  
open for it; at least I couldn't find one. But, we did put together  
some comments:

	http://wiki.apache.org/hadoop/ZooKeeper/PartitionedZookeeper

One of the main issues we have observed there is that partitioning  
will force us to change our consistency guarantees, which is far from  
ideal. However, some users seem to be ok with it, but I'm not sure we  
have agreement.

In any case, please feel free to contribute or simply express your  
interests so that we can take them into account.

Thanks,
-Flavio
