Internet users and copyright: should we have an industry code?

After three judgments between 2010-2, Roadshow has provided much needed clarity on what Internet Service Providers (ISPs) should - or should not - do when informed of alleged infringing activity by their customers. The judgments have also made useful suggestions on what an industry code for ISPs would look like. What is missing is a clearer understanding of the third parties in these debates - the public - the users. How do they use the Internet? What do they know of copyright? And if a code for ISPs is developed, how should it protect public rights to fair access to Internet content?
