SERP's cannot discover blocked content, but if a user is a 'subscriber' and they have found great content within the 'walled garden' they can 'like' it or 'tweet' it after reading it and still share it with friends, friends who can then have the choice of joining as a subscriber (or a small one off payment) to read the info people within their network on social sites have recommended ... by passing the need for SERPs.

But this is only on the condition that people on the internet start accepting that the best content is no longer 'free' and are prepared to pay to see what their friends like. It is just one theory on the future of the internet ...
