Streaming Aggregator in a Clustered Environment

I am using a Streaming Aggregator to aggregate the responses from one or more remote web services that are called from the ESB (SOA-P 5.3; esb v4.11). The web service calls are initiated from within the ESB using multiple HTTP routers.   Is it possible to use the Streaming Aggregator in a cluster and if it is, what might be involved in making it work in a clustered server setup.
