Which dispatch would itself be using methods to pass 'self' to the
receiving object.  Yes this would seem to be the obvious way to
establish two-way communication between objects.  I would be so bold
as to suggest that if the design the OP has adopted is not amenable to
this straightfoward approach, the design needs to be reassessed.
