Both processes need the same (or at minimum, a compatible interface) set of classes. All calls to remote objects are marshalled via a auto-generated proxy class and transfered to the other side.

You can mark objects with an @\ObjRef\TransferObject annotation to mark them as transferable. These objects get serialized and transfered. References in this transferobject that are no transferobjects itself are replaced by proxies.

Check out my symfony RemoteBundle for a symfony implementation and the ExampleBundle for a working demo
