Internet needs an open, integrated and universal payment layer. But first the payments should be done well (look at: Taler project), then integrations should be build, not the other way around.

I know many people here would be against anything related to payment on the Internet, but I do believe the ability to have a button like "One click here to anonymously with no account pay 0.02€ and download the media" could be a net positive for Internet freedom.
