Yes, an InvalidClientIDException is thrown on duplicate ID. It's not possible to have more than one consumer for a durable subscription - that's a weakness of durable subscriptions, although it's actually more of a Topic vs Queue isssue. Look at VirtualTopic's to get the semantics of durable consumption from a Queue when messages are broadcast to Topics, which also enables load-balancing of multiple consumers.
