Customer would like to be able just make the service persistent e.g. save the values that are exposed by the EJB3 Service MBean.

He'd like to use some very simple solution. I.E. NO XML Deploymenty descriptors or anything like that. Example:

@Service(objectName="...",persistent=true)

Currently, the only way to make MBeans persistent is by following instructions in http://www.jboss.org/community/docs/DOC-12775
