Nook DRM Removal is a commercial tool that allows to remove DRM from
Nook ebooks.
Haven't tried to use it, since freeware Nook DRM removal plug-in for
Calibre works just fine. Besides Calibre can convert Nook files to other ebooks formats, so you can read Nook ebooks whether you use
Kindle,
Sony Reader,
Nook or some other reader.
