Google plans to bring back paperback books

I've been wondering how long it would take for someone to start doing On Demand Printing of books out of copyright.

I'm really not sure how I feel about Google printing books that are out of print though. On the one hand, I think it would be awesome to be able to get ahold of some of those rare, hard to find books that just sound awesome, but are ridiculously expensive. On the other hand, it seems a little wrong to not compensate the authors, who still own the copyright for the book.

The only other question I have is: price. I think there is at least some market for cheap, on demand printing of just about any book. If I can get (throwing numbers out there) any book printed for 100 page for $0.75 (or something equivalent), with reasonable shipping, I would definitely turn that way for a large portion of my reading (rather than buying used books for essentially the price of shipping).

pg is there any chance that you could get On Lisp printed this way? I know its not out of copyright, but you have freely put the pdf up on your site.
