From Paidcontent.org: "Startup iPad publisher Inkling has just launched a free, cloud-based, interactive e-book publishing platform, Inkling Habitat.
Inkling Habitat is a program for professional publishers producing e-books at scale, and a way to make a very expensive process more affordable.
Inkling Habitat lets publishers create interactive e-books with HD video, interactive features and 3D content in a free, cloud-based program.
E-books can immediately be published to iPad and the Web in HTML5, with updates pushed to both platforms at once. (Well, iPad is available now and Web publishing will be added later this year.)
Multiple groups can collaborate on the content simultaneously and every version of a publication is saved, so changes can always be rolled back.
The program is free, but in order to use it publishers must agree to make the books they create with it available through Inkling’s store (in its iPad app and on its website). Inkling takes a cut of the revenues from those books. Unlike with iBooks Author, publishers can also sell the books they create through other channels (their own websites or as individual apps, for instance) and Inkling does not take a cut of those sales."
