Class hiarchy:

---
Event
   EventNotification
      EventNotificationUser
---
Each class calls
boost::serialization::base_object<...>(*this);
and has
BOOST_CLASS_EXPORT_GUID(..., "...")
at the end of their header.
>From what I can gather from the manual this is what's needed for boost
to know the types and be able to serialize them, but I still get
"unregistered void cast" exception when I do this:
EventNotificationUser e;
Event* ep = &e;
ar & ep;
Thanks,
Christian
