You can just copy a book with B&N's DRM to an unlimited number of supported devices. If you open the book it will ask for the credit card number and name the book was encrypted with. Anyone who knows this information (the social part of the DRM) can open the book. The key generated by this information will be stored on the device, and other books encrypted with the same information will open immediately.

This was definitely how it worked for fictionwise/ereader (a strong factor in my 8 yrs of patronage of ereader.com -- drm that doesn't phone home is better than drm that does. learned that the hard way), but since Nook introduced its time-limited book lending, I assumed B&N made changes or switched what DRM they used. Else how can they limit how many times you lend the book and how long it's readable?
The only alternative I can think of is that only lent books get a different DRM wrapper protected by more than just social DRM. Any idea what the impact on lending is on their DRM?
