I’m actually attempting to do something similar. Post: http://www.magentocommerce.com/boards/viewthread/8254/
When I figure out the exact steps that need to take place and can confirm what files need to be modified, I’ll see what we can do to help out on this.
Off the top of my head, we’ll have to modify the shipping method and possible XML to insert a condition. We may need to check for the included product attributes that have been selected, and then run through a condition if a certain product with that attribute is sitting inside the shopping cart.
Definitely doable, though I just need some confirmation on a few things prior to getting on something like this.
