I have said on many occasions that you should use DRM removal tools not so you can pirate the content, but so you can protect your purchases. And that is why I'm posting about this new hack.
You can find the KPR hack as part of the latest bundle of DRM removal scripts. It's over on the Apprentice Alf blog, but you need to know where to look (here). That site is being quietly maintained by someone, and out of appreciation for their work I have not pried too deeply.
The ZIP file that they're maintaining over there is actually a bundle of scripts that can remove the DRM from a number of ebook formats, including Kindle, Nook, Mobipocket, eReader (the really old format), Epub, and PDF. It doesn't appear to support iBooks yet, but that's okay (it's a minor format).
