How to have a nested inline formset within a form in Django?

I hope this question has not been asked yet, but I want to know if it is possible to have a normal class-based form for an object and to have an inline formset inside it to edit its related objects.

For example, I have a Contact model

class Contact(models.Model):
    ...

And a Communication model

class Communication(models.Model):
   contact = models.ForeignKey(Contact)

and I want to have a form for Contact with a inline formset nested in it for managing communications related to it.

Is it possible to do so with existing components or do I have a hopeless dream?

EDIT : I know that the admin panel does it, but how do I make work in a view?
