Java Virtual Clusters? Extend JEE Spec to Clusters

When will we get a real extension of the JEE specification to include clusters?
A specification to define things like:

• JMS behavior in a clustered environment to include issues like distributed queues and topics as well as message load balancing
• JNDI real-time namespace linking or sharing across a cluster or set of clusters, foreign JNDI providers
  
• UDDI cluster behavior
• RMI load balancing across clusters
  
• WS invocation load balancing across clusters
• Multiple JVM coordination, scaling, JVM lifecycle management
• Datasource management across clusters
• Security and Identity management, authentication across clusters
• Persistence and other state management or caching mechanisms
  

And anything else that causes so much customization to occur in JEE applictaions that write once run anywhere simply breaks down and is lost when it comes to JEE world.
