Hi Jules,

I guess - I understand that just any ole string is not a destination  
but we are (or would be) using the destination Strings from  
ActiveCluster. As far as I can tell we never cook our own  
destinations and if we ever do actually need a destination we can use  
the Cluster's createDestination method which would delegate to the  
particular impl technology (i.e. if we had a multicast impl, or a  
different JMS than AMQ).

As I understand the move to String it was related to Destination not  
being Serializable on all platforms (i.e. sonic's Destination). So  
given that and in the spirit of providing choice to our users  
wouldn't it make sense to leverage the work AC has already done in  
this area to achieve impl independence?
