1) Yes I think incentive structures are a part of it. For us as authors,I know I typically think about the website very differently than the book. Having an editor peer review also helps keep me focused. What you find with a lot of open source coders, they tend not to always be good writers (me included). My book is 530 pages and took 2.5 years to crank out in between new releases. My company funded the book's development more as a loss leader. Authors don't make crap from the royalites. You're better selling it as part of a larger package such as training or support.

2. You have to know the right people. Go to the conferences and ask them. It took a long time. The profit shares aren't much. I more did it for the exposure at their conferences. We found it to be worth it as part of a larger package and networking with others in the field more than anything else. The notoriety has really helped as well. It's a lot of work, but definitely worth it if you can get it. Just be ready to put in a metric ton of work.
