If I get some time soon I will.

This is basically the class:
class User
{
public:
    User(std::string name, std::string pass)
        :name_(name)
        ,pass_(pass)
    {}
private:
    std::string name_;
    std::string pass_;
}

And it could not be serialized through a smart pointer

I can try to finish wrapping the rest (seemed pretty easy,
Boost.Serialization already has things to handle basically all
stl-style container types, it just was not yet exposed to the new tr1
version, but seems to work perfectly with them) and do that after
testing that they work, but it may take some time, I get free time
about once a week (last night for this week).
