No.

I want you to have:

    *one* protocol, registered in proto_register_s5066dts();

    *two* dissector routines, *both* registered in
proto_reg_handoff_s5066dts(), which *share* preferences and header fields, but
have *different* handles:

void proto_reg_handoff_s5066dts(void)
{
    static gint initialized = FALSE;
    static dissector_handle_t s5066dts_handle;
    static dissector_handle_t s5066dts_over_tcp_handle;
    static int currentPort;

    if (!initialized) {
        s5066dts_handle = create_dissector_handle(dissect_s5066dts,
proto_s5066dts);
        dissector_add_uint("wtap_encap", WTAP_ENCAP_STANAG_5066_D_PDU,
s5066dts_handle);
        s5066dts_over_tcp_handle =
create_dissector_handle(dissect_s5066dts_tcp, proto_s5066dts);
        initialized = TRUE;
    }
    else {
        dissector_delete_uint("tcp.port", currentPort,
s5066dts_over_tcp_handle);
    }

    currentPort = config_s5066dts_port;

    dissector_add_uint("tcp.port", currentPort, s5066dts_over_tcp_handle);
}
