Print on Demand for Out of Print Books

I was alerted by LISNews.Org about this "Amazon's print-on-demand division "BookSurge". It is not so much of the content of the story, it is not new, that I want to write here as I could foresee this happening in the industry. Obviously there is a good business case and model for this kind of thing and Amazon, if not Google, is big enough to sustain it.
