Is this a request for clusterwide EJB Singleton or a generic Singleton Service. If the latter, any application object can be a singleton using a generic service that is cluster aware through GMS - a feature we have been thinking about in Shoal.
Would help to clarify what is being sought here.

The state-management JSR (being proposed now) will provide this feature. There already exists implementations including Coherence, and eventually we would like to have a Shoal provider built as well.
