Okay I can see your point... Just remember that when your node dies (machine crashes), you loose both the queue and a message consumer (processing power). This is the reason why we chose to deploy our consumers on separe JBoss instances.

(I think some kind of 'load' indicator exists in de clustered jboss-instances). Does that help?
