Update. Also see the announcement from the National Library of Sweden. It adds these new details:
...All libraries involved in the licensing consortium that have High Energy Physics on the research agenda of their parent organization have expressed their interest to participate in the SCOAP3 and contribute to the financing of it by diverting potential reductions in subscription costs.
The Swedish participation has also been formally supported by the Swedish LHC Consortium and the Board of the Section for Elementary Particle and Astroparticle Physics of the Swedish Physical Society.

The open access movement:
Putting peer-reviewed scientific and scholarly literature
on the internet. Making it available free of charge and
free of most copyright and licensing restrictions.
Removing the barriers to serious research.
I recommend the OA tracking project (OATP) as the best way to stay on top of new OA developments. You can read the OATP feed on a blog-like web page or subscribe to it by RSS, email, or Twitter. You can also help build the feed by tagging new developments you encounter.
