Shipping question

I asked this question already in the MV forum: [url][/url] but I am wondering in general from the rest of you here - if suppliers have been removed from the MV version and this is not possible how would you have different shipping methods for different products or categories in general?

Obviously I want to have a shipping method for vendors for light products (envelope size) and heavy items (say over 3-4 lbs) - in non MV versions I created suppliers. If you dont use suppliers, is this possible to setup?
