Guyon - Awesomium only does Windows, Mac and Linux desktop. For Android we're looking in to directCanvas and CocoonJS, but I'm not sure if they work on a Nook.
Nook Color & Nook Table are propitiatory android device, so unless you Root them they will not pick up any Android market.
Nook Color can run HTML on it, but like the PC does not like to run a html game directly. Is there easy way to run an HTML game without the web?
