Validating or modifying admin inlines against main form

[graeme]

I need to do one of the following in the admin using Django 1.2:

1. Validate a value in a form against which objects have been added
using an inline form.
2. Add or delete related objects depending on the value in the main
model from.

The first would be preferable as the user would be able to decide
which was wrong and correct it appropriately.

I have tried doing this using the model's clean() method, its save()
method and a post_save signal. In all cases I cannot get the new
related objects.

I have thought of using form validation, but I cannot figure out how
to get the values from the inlines in the validation of the
ModelAdmin.form.
