With both the Kindle DMR and the Adobe ePub DRM you cannot just copy an ebook file to any ereader.
Kindle books are tied to the hardware ID of the ereader. Every ereader you want to read a Kindle book upon must be tied to your account, and a version will be downloaded that can only be read on that specific ereader.
Adobe ePub DRM ebooks can only be read on an ereader that is authorized with the same Adobe ID as the book was originally downloaded with.

So both DRM's are a lot different than the B&N DRM. Once a B&N DRM ebook is downloaded you can just take the ebook file and copy it to as many ereaders as you want, as many times as you want.
You do not have to tie the ereader to an account to download a new version. you do not have to authorize the ereader in any way. You do not need any DRM server, in any way. Every book is a standalone file, that does not need anything else to function.
