Hello Jim
Unfortunately I can't confirm it's working
Using  activemq:failover 
I've got :
"Connect fail to 'discovery:multicast://default': Composite connection not 
supported with MulticastDiscovery transport."

Using activemq:discovery:multicast://default I've got:

Connect failed :Apache.NMS.NMSConnectionException: Unable to find a
to discovery:multicast://default before the timeout period expired.
   at Apache.NMS.ActiveMQ.Transport.TransportFactory.CreateTransport(Uri 
   at Apache.NMS.ActiveMQ.ConnectionFactory.CreateConnection(String
String password)
   at Apache.NMS.ActiveMQ.ConnectionFactory.CreateConnection()
   at ActiveMQConnector.MQ.Connect()

Tried again trunk from today.
Can I help you with more information or anything else?
