Or course they are not using B&N DRM. That would be stupid IMHO, when most shops selling ePub uses adept DRm. And barnes and noble being US only, I coudn't care less about not having acces there. You're seeing this from a us point of view, but using B&N drm means losing everyone not the the US.
Sounds temping, if they add justify for ePub, it might be mine.
