True, but consider also that dynamic_cast has a different interface:
template<class Target, class Source> Target dynamic_cast(Source);
so even if we could overload it, the syntax would have been
shared_ptr<X> px = dynamic_cast< shared_ptr<X> >(py);

This doesn't look too good if you consider the possible boost->std
