How about some good online sales tools for ebooks? (Score 1)

I've seen a lot of good conversion software, but not a lot of really great methods for authors to do the actual selling on their own. Especially in regards to free or low-cost open-source methods. I'd love to see a complete solution that offers the chance to collaborate and construct an ebook over the web entirely from scratch, then approve and publish it to various formats on your own website, and offers many methods to tailor the method of sale -- specifically pay-what-you-want options and integration with different payment processors. I like the idea of authors being in control of every step, beholden to as few middlemen as possible.
