If you take the subject and event example and scale that up ten fold so that the object has 20 methods instead of 2 the code quickly becomes hard to maintain and the size over the wire increases quickly. I think what Ihab said points this out clearly and without a good forwarding mechanism ZI seems unmaintainable.
