Authorizing NOOK® via Adobe® Digital Editions

I think what most people seem to mean when they say an ereader has ADE is that you can use a web browser on your ereader to directly download an epub using an .acsm file. Being able to authorize your ereader and read an epub transferred from ADE on your computer using USB or wireless is not quite the same. RMSDK is not ADE.
