Hi, We are not going to be able to support load/store state operations with TcpCacheLoader so easily since we can not serialize stream handles to remote delegate cache. I will leave load/store operations throwing UnsupportedOperationException and TcpCacheLoaderTest is an expected failure. It seems like it will be a similar case with rpc and rmi based cacheloaders. We have to think of a solution for these cases that will not be a kludge. Vladimir
