Yup, the destructors are virtual (and dynamic_cast is working in both directions). However, it works now (see later 
comment).

Nifty. I swear that didn't compile when I used it on Friday, but now it does. Now that I have changed it to that 
format, ar.template register_type<derived_one>(), it works. Out of curiosity, what is the difference between calling 
it that way and calling ar.register_type<derived_one>()? I've not seen that type of format and would be interested in 
learning more about it.

Thanks again,
