I think Google might be working on something. When I visited an Australian Fairfax newspaper yesterday (WA Today), I got a prompt inviting me to 'subscribe' to the newspaper via Google Contributor, which I was able to do. They're charging 1c per page view for an ad-free experience.

I think I only got the prompt because they detected I was using an ad-blocker though. I'm not sure it's open to everyone yet.
