    When do I use UnicastRemoteObject vs
    PortableRemoteObject?

    UnicastRemoteObject should be used as
    the superclass for the object
    implementation in RMI programming.
    PortableRemoteObject should be used in
    RMI-IIOP programming. If
    PortableRemoteObject is used, you can
    switch the transport protocol to
    either JRMP or IIOP during runtime.
