some questions about IceStorm Replicas

In Ice Manual, show us as following.

"There are two ways of deploying IceStorm in its highly available (replicated) mode. In both cases, adding another replica requires that all active replicas be stopped while their configurations are updated; it is not possible to add a replica while replication is running."

That means that all my services using the IceStorm must be interrupted? Is there any way to avoid such a thing happen?

我想，将ice register用zookeeper来实现，将会解决ice长久以来不能动态部署的问题。
