Network LOOP

Hello everyone!

I'm currently working with Shopp plugin to create a network of small e-Commerce platforms. I already have a few customers using their Shopp accounts on my network and they seem to be very happy.

I would like to create a global product catalog on my main site that takes the products from all of the network sites.

Is there any easy way to create a global network loop to get the data from all the sites?

Thanks in advance and best regards!
