I don't know of a app server that can do this. Even though this is easy to implement (no different than being able to shoot the codebase of ejb stub implementation classes across the wire), I assume most vendors will not do this due to security concerns. A JMS server, on the other hand, can do this (ObjectMessage) simply because the server is a conduit and never "opens" the message package.
