how to populate loop with global products?

Hi, this may be a tricky issue but I'll try to explain as clear as I can:

We are testing MarketPress in a multisite where the main site will serve as global marketplace. Nothing special here.

We use the theme Portfolio Press which normally shows a post type 'portfolio' in a neat gallery of images -- but we adapted it so that it now takes the post type 'product' instead. This works very well to show a clean grid of products images on the home page of any shop in the network. This is done with a common:

$args = array(
	'post_type' => 'product',
	'posts_per_page' => $posts_per_page,
	'paged' => $paged );
query_posts( $args );

So far, still no problems at all.

But now we'd like to use the same theme (or at least the same method) on the root site of the network to display Global Products. The main site does not have any products of its own so right now the front page shows no images in the grid.

Would it be possible to populate the query with global products instead of the site specific post type 'product'? Or do we need to construct a whole new template based on/around a function like mp_list_global_products() or similar?

Thanks for any pointers :slight_smile:
