I had heard this about a Netflix contract stipulation as well, and actually, that's what started my post about v1.4.1 in the nook color section. That particular version now offers Netflix on the NC too.
But is this Netflix HD on the Nook Color? If so it throws a whole new light on things. In any event, the team on XDA Developers is still dissecting the mysteries of the NT, and making some progress. It's just unfortunate that the early negative posts about the NT's rootability (on XDA) may have dissuaded some of the enthusiasts from participating. There are I think only two or three people with a high level skill set working on the NT. Could have been more.
