Translation of eCommerce products

I'm trying to create a bilingual shop with i18n and eCommerce. I'm not sure, whether this is a i18n or eCommerce issue, though...

When I create an eCommerce product, I can choose its language. Now, when I select «translate» from the tabs I get sent to a page where I can select what type of product I want to create instead of right to the page where I can enter information. I know, what product I want to create (the end user won't), but this step shouldn't be necessary. Anyway, I select my product-type and create a translation. Unfortunately, by this time, i18n seems to have forgotten, that I'm trying to translate something and the products' translated counterpart doesn't show up. I now have to manually select, what node is the translation of my original node. This just isn't an acceptable workflow for my end users.

So, I figured out, that translate.module, when creating an «add translation» link, only puts «product» as node type into the url, what would be needed is something like «node/add/product/apparel/translation/63/add». But that wouldn't work because translate.module gets its arguments via the arg() function.

Now, I don't know, whether this is an i18n (or eCommerce) thing that can be fixed. Should I better give up and create separate shops (maybe via taxonomy)? Or can anyone point me into the right direction? Thanks!
