Brought to my attention by an LJ friend:
"The machine can print, align, mill, glue and bind two books simultaneously in less than seven minutes, including full-color laminated covers. It prints in any language and will even accommodate right-to-left texts by putting the spine on the right."
Pretty cool idea, in my opinion. Choose the book you want and it'll print it in 7 minutes or less. Granted the 550-page cap provides some limitations (or a lot, if you're into long reads), but they're planning to work on that.
Personally I'd like to see this.
