[Boost-users] [serialization]

Hi, I still got some starting problems with the boost::serialization library. I want to serialize a shared_ptr to my own polymorphic class. I'm building my own networkprotocol and the basic idea is a kind of "header"-class which with a shared_ptr which can point to a lot of different data structs, which are polymorphic children of data_base. This "header"-class is then serialized and send to another peer. But how should this peer get the real type from the shared_ptr? Which child is it pointing to? I can get the name with "typeid()", but i cannot get the type through that way. I would like to get the type from it automaticly without using some case-conditions, so i only have to add a new child of data_base and can use it, without changing any networkprotocol related code.
