Currently (afaict) there isnt a specialization of remove_pointer that handles smart pointers.

Providing a very generic specialization:

template <typename T, template<typename> class Ptr> struct remove_pointer<Ptr<T> >;

or a set of specializations that cover shared_ptr etc + auto_ptr explicitly, "seems" like a rational extension.

Are there any potential problems, and if not can we get this added to type traits?

That could break reams of code, and I would try very hard to stop it from happening. The type traits operate on _fundamental_ type properties as given by the C++ type system. A smart pointer type is not a pointer type; it is a class. -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
