You should be able to get the complete list of services using a ServiceTracker. So a nice way to create a load balancer should be to create a proxy service yourself that does the load balancing and publish it locally as a service with a special property. So your business application can use the service without knowing anything about the details of load balancing.

Load balancing is a concern that is meant to be implemented by the Topology Manager (TM). It would be useful to read the Remote Services Admin specification, which addresses exactly this kind of question.

As far as I know, the CXF implementation of Remote Services only implements a single TM, which is "promiscuous", i.e. it publishes every available service in every listening framework. It is possible however to write your own TM to perform load balancing and failover etc.

The Remote Services spec is written in such a way that a TM implementation can be developed completely independently of any specific Remote Services implementation.
