	Fixed, good call, no one knows. Shrouded in the mists of time. It
does now.

	It could be, but it is unneccessary. The situation you suggest can
be achieved with the creation of a BonoboObjectClient and aggregating that
in the normal way. The situation you propose has never arisen, and we are
interested in making the common case easy, fast and simple. To do as you
suggest would involve not only adding an 'add_interface' method, but also
a 'get_interface_list' interface too, and add much complication to what is
currently quite a clean piece of code.

	Do you really want to do this ?
