So far so good - look at the serialization implementions for std::vector<T>

and others.

That would be the way to do it. However, someone proposed a solution

to this problem and uploaded it as a track item. I found it intriguing,

But I decided not to implement it to keep the library from getting

any more complicated than it already is. You might want to

paste this proposed enhancement into your own code.

lol - this is an understatement

The rub here is your requirement that it be exported through

a base class pointer. Were it not for this, it is easily done

just like standard containers are.
