I've been testing with a kind of api/script that allow you to upload products in your store with a simple link.
English version: http://en.otcommerce.com/products
Russian version: http://box.otcommerce.com/
after introduce the external link of the product, the api upload, translate, calculate, everything, and you will be able to modify / edit whatever you want.
Actually, upload a single product is a hard process that require a lot of time. with something like that, we could have thousands of products ready to go in a very short time.
