Although it's meant for just the Nook Color at this point, B&N released the Nook SDK
http://nookdeveloper.barnesandnoble.com/tools. There's probably no chance I could connect it to my rooted e-ink Nook at this point, is there? I read somewhere when they first announced the SDK that they would make it available for e-ink Nooks sometime later. Hopefully they'll do it before my Nook goes obsolete!
