WP 3.0 + Custom Post Types + Custom Post Type Taxonomies

Has anyone experimented with integrating the new "Custom Post Type Taxonomies" available in WP 3.0 with a GF?

The code that generates a meta box for Custom Post Type Taxonomies within the Wordpress Admin seems easy enough:

foreach ( get_object_taxonomies($post_type) as $tax_name ) {
	$taxonomy = get_taxonomy($tax_name);
	if ( ! $taxonomy->show_ui )
		continue;

	$label = isset($taxonomy->label) ? esc_attr($taxonomy->label) : $tax_name;

	if ( !is_taxonomy_hierarchical($tax_name) )
		add_meta_box('tagsdiv-' . $tax_name, $label, 'post_tags_meta_box', $post_type, 'side', 'core');
	else
		add_meta_box($tax_name . 'div', $label, 'post_categories_meta_box', $post_type, 'side', 'core', array( 'taxonomy' => $tax_name ));
}

Any ideas how to get that to display on a GF?

Alex, that's exactly what I'm trying to do. Sorry for not explaining better :)

Is there by any a chance a way to do it now using GF hooks?

Any update on integration with 3.0's custom post_types? This thread is 3+ months old and WP 3.0 has been out for a while now....

I need to build forms that create posts that are specific to each of the unique post types that my site has.

Thanks in advance for the update.
