Well, you _could_ have multiple MDBs consuming from a single live JMS server - this is the old JBoss MQ style approach where you only have one active server in the cluster at any one time, nothing is stopping you from doing that if you want. Alternatively just have MDBs always consuming from their local servers, use clustered destinations, and message bridge to route messages between geographically distributed clustered (e.g. over WANs).
