But, why not just give your users an access to their webshop Administration area?

Its better you to create module for add products by users from their my account area. Check the saveAction in Mage/Adminhtml/Controllers/Catalog/ProductController.php .You may get more idea how to save product.

If you are planning to add only some members to add their products through backend, its better you to create users and assign permissions to add products from backend.
