The expirity check seems working fine to me if merged in 
enable_shared_ptr2 and solves some problems.
I can summarize other boost::python's problems in this example:

class X : public boost::enable_shared_from_this2<X>
{
public:
    void test()
    {
       shared_ptr<X> me = shared_from_this();
       BOOST_ASSERT(me);
    }
};

void expose_x()
{
    boost::python::class_<X>("X", boost::python::init<>()).
       def("test", &X::test);
}

------------------------------------

C++ case 1 (works fine):

shared_ptr<X> x(new X);
x->test();

------------------------------------

C++ case 2 (doesn't work because of the missing static/dynamic cast):

X x;
x.test();

------------------------------------

Python case (doesn't work, same problem of C++ case 2)

x = X()
x.test()
