JMS might be an interesting approach, too. Underlying queue managers usually offer "persistent queues" or "assured delivery" that solve some problems with your singleton server availability. If the singleton is down, requests stay in queue until it comes back.
Could the singleton be in its own application that is not duplicated across the cluster?
A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi
