Hey Larry, Thank you for your response! Are there any examples out in the wild on how to do this? Also the part that is confusing me is the name resolution. Do we have to add a custom name resolution policy as well so that we get both the LB and round robin IP addresses in `acceptResolvedAddresses <https://github.com/grpc/grpc-java/blob/master/examples/src/main/java/io/grpc/examples/customloadbalance/ShufflingPickFirstLoadBalancer.java#L66>` method in the LB policy?
