Access parent fields in child submission form?

Hi!

I would like to have the parent node's title displayed on the child node's submission form. I get it to show on the actual child node editing the content type template, but can't figure out how to do this to the submission form. This'd only have to apply to certain node type.

This is not crucial to work, but would be a real conviniency :)

kthxbye
