boost::shared_ptr and NULL

In this function declaration, is there a simpler way to express a null shared pointer as the default argument value?
  void foo( const boost::shared_ptr<T> & p = boost::shared_ptr<T>( ) );

In this function call, is there a simpler way to express a null shared pointer as the actual argument?
  foo( boost::shared_ptr<T>( ) );
