While I can't answer your question directly, I can tell you that this is bad coding practice in C++. Usually it stems from a misunderstanding, while other times it's just a bad design.
Have you considered type traits. Don't know how that works with python though. template<class T> struct policy { static const bool value = false; }; struct policy<A> { static const bool value = true; }; There's an interesting tutorial here: http://www.cantrip.org/traits.html
So, to summarise, any idea how to provide polymorphic Python class variables in boost::python?
Static/class fields cannot be polymorphic, by definition.
