Following a suggestion from another thread, I have tried broadcasting in a polymorphic way.

I have a hierarchy of polymorphic struct (they have 2 virtual functions). I was wondering if it was possible/allowed to

root process:

base* b;  /// b points to an actual derived struct but may also point the base struct (not abstract)

broadcast( ..., b, ...);

slave processes:

base* b;

broadcast( ..., b, ...);  /// broadcast constructs the appropriate struct and makes b point to where it did that

assuming all the conditions for pointer to class conditions are satisfied for the serialization library.

Otherwise, perhaps a solution with a boost::variant over the base struct and all of its derived is the way to go?

Thanks,
