`std::vector& Doc::foo()' is protected

This is not a shared_ptr problem. The same thing would happen if you were using Doc *. You could fix it by using Doc const *, and in the shared_ptr case you can fix it by using boost::shared_ptr<Doc const>. Or you could fix the problem by using different names for the const and non-const foo() functions. Your original design shows some confusion about C++ rules about access control. Making something protected does not affect whether it's considered when doing overload resolution, so it's impractical to have a pair of const/not-const functions overloaded the way you do. -- Darin
