Examples of successful opt-in implementations

Out of curiosity, on today's call two examples of "successful" opt-in
implementations were given.

1. was the financial times - http://www.ft.com/home/us. This shows a popup
saying the following: "FT Cookie Policy

we use them on our site. To learn more about cookies and their benefits,

Before you even accept anything, I counted 40 cookies being set, including
18 from Financial Times. FT itself used HTML5 local storage in addition to
the 18 cookies.

2. The other was the UK CIO's site -- this seems to be down at the moment.
www.cio.gov.uk redirects to some archive page. Taking another government
site as an example, I see 7 cookies including GUIDs from
http://www.cabinetoffice.gov.uk/content/privacy-policy

So, I'd like to re-raise my question of whether anyone has actually
successfully managed to deploy an opt-in compliant website in the wild...
