I wonder if this will mean that European scientist will only be allowed to publish in open access journals or if it will be sufficient if copies of the papers are made freely available. The APS, who publishes the Physical Review journals which are some of the most important in physics, for instance already allows authors and their employers to post their papers online free of charge [http://journals.aps.org/rmp/copyrightFAQ.html#post http://journals.aps.org/rmp/copyrightFAQ.html#post]. In my field everybody already puts every paper onto the arxiv anyway, so open access is almost a lived practice.
