What's the matter with my propose solution below of using the archive type 
as the "flag"?

If necessary you could define a special type of archive - 
confguration_data_archive
and a simulation_data_archive. These would be "boiler plate" code modeled on
the code from text_oarchive.hpp (or binary or) which would have the effect 
of
creating a special archive types.  These types can be used to dispatch the 
appropriate
serializer.

class Foo {
    void serialize(confguration_data_iarchive & ar, const unsigned int 
version);
    void serialize(confguration_data_oarchive & ar, const unsigned int 
version);
    void serialize(simulation_data_iarchive & ar, const unsigned int 
version);
    void serialize(simulation_data_oarchive & ar, const unsigned int 
version);
};

or if you want to get fancier you can use MPL type techiniques to make it 
slicker.
