Whatever way it's applied or not, the idea of fair dealing is to give a bit of oil to the system to let people make a couple of copies of a book, or so on. Are you looking to clamp...? Do you want to make money, monetize every single copy, or are you against...?
Can you give us your view of what fair dealing should be? You're not happy with what it is. Should it exist, number one; and two, if it does exist, how should it exist?
