James Duncan Davidson and Mike Clark has delivered on their first large, commercial Rails project together: VitalSource Bookshelf. It’s a book store that aims to make it as easy to buy your ebooks as your music. What’s special is that it includes a native application, ala iTunes, that works together with the Rails-powered store.

On James’ announcement, there’s also a note from Willie Abrams of VitalSource. He writes about using Rails: “As for Ruby on Rails? Wow. A lot of things would have to change for us to consider doing a web application any other way. It is that good.”.

Thanks, Willie. And congratulations to both Mike, James, and VitalSource for shipping!
