- Use shared_ptr for both _var and _ptr.

    std::shared_ptr<FooFactory> factory = // get a Foo factory
    std::shared_ptr<Foo> foo = factory->make_a_foo("my foo");

   Or even the now evil:

    factory->make_a_foo("my foo")->do_something(); // currently leaks

   _narrow will still be needed since you need the server's help.

- IDL string is std::string
- IDL sequence and array are std::vector
   - Java maps them to the same thing

   std::vector<octet> object_id();
   std::shared_ptr<Object> id_to_reference(const std::vector<octet>&);

   C++0x allows std::vector to be returned via std::move without cost.

- No exception specs

- Forget backward compatibility. Consider it a new language. It
doesn't replace the current C++ mapping it is a new language mapping for
Modern_C++. So vendors can support either one or both. Just like
vendors can now support C++ and Java and Python or just Java, etc.
