It shouldn't be difficult to implement, and it should even be able to support character/phrase location if going that route(most likely going to be pretty slow in generating the x-ray file though). But Amazon has been rolling out more & more books with X-Ray, I'm not seeing any long term usefulness for the x-ray file generator in the future(perhaps just for people's DRM free books). Also calibre uses Python I think? which means I'll have to look it up & familiar myself with that
