Federico,
This is a really neat initiative and brings together a lot of thinking around oa repositories, indexes, apis, citation practices, and author engagement.
I have one request if you don't mind...
Could you share the email text that you're using to send to authors with this group?
I am not concerned if publishers don't like this project, but I wouldn't want them to be upset just because language gave them a misunderstanding about how Wikipedia treats copyright (which is we treat it appropriately, and share freely whenever possible).
Thank you,
Jake Orlowitz

Federico,
This is great news! You are showing the way. I look forward to many more such initiatives, not just in Wikipedia, but anywhere people look for access to knowledge.
The "brand" of Wikipedia is all about having "every single human being can freely share in the sum of all knowledge". There are many organizations, commercial and otherwise, that espouse a commitment to "open". Finally you (and the shoulders you are standing on) are showing how we can systematically message authors to share. This has the real possibility of breaking the monopoly control and pricing of access to knowledge.
Good job.
