You can only declare a single Dao implementation per DaoManager. This
is due to the fact that the Dao interface name is used as the key to
lookup the implementation. I think the easiest route for you may be to
extend the interface of your Daos interfaces that are shared. That way
you will have a unique interface for each yet they can have the same
implementation class.
