[boost] [serialization] The constant object problem

Hello everybody,

I've read the rationale for only allowing const trackable objects, but 
here is my problem :

I want to serialize the following class :

class C : boost::noncopyable
{
public:
   void setData(string s) {data = s;}
   //...
};

int main()
{
   C c;
   c.setData("Hello world");
   vector <C*> v;
   v.push_back(&c);
   //...
   ar << c << c;
}

To have a c with meaningfull data, it cannot be const.
I cannot create a local object that is a copy of the object (it is 
noncopyable)
I do not think making the object untracked would be a good idea in this 
case (I might be wrong ?)
So far, the best way I found to be able to serialize this object is :

C const & cForSerialize = c;
ar << cForSerialize << cForSerialize;

But I do not think this is really elegant code. Is there a better 
alternative ?
