Yes, this is how it works now. The client side of the HAIL uses the singleton notifications, which in turn use the DRM. The question is how to implement the client stub so that it does not have to be part of the cluster.
The smart RMI stubs take care of communicating with the back end to receive regular snapshots of the cluster view. There has to be additinal info about the current singleton server. As Scott mentioned this can be probably done as an extension to one of the load balncing policies. However UIL2 does not use the smart RMI stubs. How to merge them? Just use the RMI stuff for HAIL and don't worry about UIL2 for now? Is the existing remoting at a stage that can replace UIL2 without any loss of benefits ? I am not familiar with it yet.
