How to have an "administer product category" role
Do you have any hints about how to allow users having the "seller" role to create/edit/delete products(and product displays) for a given category? (or maybe with a given user-reference or anything that will be easy to mantain)
I was trying nodeaccess_nodereference/nodeaccess_userreference but products are not nodes so this doesn't work.

You could have a different
You could have a different product type (admin/commerce/products/types) for each category. You'd then have to create a different role for each product type that allows editing and creating that specific type. Then assign the user whatever roles go with what types they can edit.
