I understand your viewpoint. I also dedicate a major share of my free time to "honorary work" (like leading a boy scouts group for the last 11 years for example
) and I like the idea of sharing knowledge. It's just that I need the time investment into SOME projects to pay off (in the strict sense of the word), so open source is not an option for me at the moment.
Still I'd like to listen to potential user requests to make a better product - and I figure that many of you might be interested!
Besides, booksorber will be cheaply priced, and I hope it will be an attractive solution for people who typically have some camera equipment available, but no time for building more evolved scanning rigs.
