Following various links for the piracy debates, I came across this blog entry. It tells you how to combine some scripts with calibre to strip DRM off of your books purchased from Amazon, Barnes & Noble, etc. etc. It doesn't work for LIT books or iBooks with DRM. I've installed it and used it and it is quite easy.
ETA: If you don't enter the correct information for the plug-ins, you will have to remove the books that still have DRM, fix the information for the plug-in and then, re-add them to calibre in order to remove the DRM.
