Better handling of attributes in Product Kits

There is something very confusing about Product Kits which include products containing attributes.

For example, let's say I have a Product Kit which contains 6 Packs, and each Pack has an attribute for T-Shirt size. On the "Add to Cart" form, if I select a T-Shirt size option, then click submit, 6 Packs of the same T-Shirt size appear. My desired behavior is to be able to select a different option for each Pack in my Product Kit.

I am submitting patches to the uc_product_kit.module and uc_attribute.module which will add support for this behavior. Instead of showing one Pack with it's corresponding attributes, it will display 6 Packs (or whatever the quantity is for that product) and give the user the ability to choose a different option for all 6. At the time of adding to the cart, if any of the options are the same (for example, a user chooses 3 larges, 2 mediums, and 1 small), these products will be merged and appear as single line items in the cart with the proper quantity.

The only additional modification which may need to happen is to give the user the ability to customize this behavior on a Product Kit basis. But that should be easy to integrate (maybe through an additional column field in the uc_product_kits table, and a set of radio buttons on the Product Kit node form). Let this ticket be a starting point for some better handling of attributes in Product Kits.
