hmm... Not really... from your point of view, think about this: I want
to edit the children from the parent admin view, and *not* assign
parents to children from children's admin view....
Do you see? the relation is the same, but from the other side.
I think I'm going to need a custom field/widget for this.
Thanks for your help.
