	Ok - so, there is no free way of development ;-)

	Arguably - it's best for an object to have a PersistStream interface,
and be able to persist itself to a stream somehow, rather than it being
done via serializing the PropertyBag.

	How do you get at the 'other' data ? how do you get it's type
information to serialize it ?

	Properties are arbitrary blobs of data that can be associated with
programmer readable string names, and 'stored' in a PropertyBag -
although storage should never be in the 'BonoboPropertyBag' but internal
to the object.
