The printed book will be linear with the option to skip to required sections. The online version has the navigation templates. It might be useful to have a navigation template with links to relevant sections in the separate cross-cutting chapters) - perhaps a table at the foot of the page with relevant section links and comments.
Mobile Access is a cross-cutting concern. Move it into its own section/chapter.
"Composing Learning Resources from Multiple Sources" should go directly under "Compose" which could have sub-sections - see thoughts on structure.

It's not just a matter of subject material being presented in a linear fashion, but conceptually linear. In the introduction we do say that readers can jump to any point. However, to accommodate educators or learners who don't have much experience in learning object creation, I think the OER lifecycle needs to be fairly simple (but as you say, only simple enough) for them to understand.
I have also posted more on "thoughts on structure" Talk page.
Thanks for the comments. I have edited this page substantially, ... please check that I have not deviated too much from the style.
