Following up on George's post, here's the DeRPC doc. You can find a little additional info by searching for "DeRPC" on the public issue tracker. DeRPC was created to help with large object graph serialization; however, DeRPC (NOT GWT-RPC) will likely be deprecated eventually in favor of RequestFactory.
