While the NOOKcolor (we spent a week with the device, [click here] to see how it went) has already been rooted, and owners can now install games like Angry Birds onto it, the news for developers that the first version of the NOOK Software Developer Kit is now available should be good indeed. It will provide developers with the tools necessary to take full advantage of the eReader, and unlock any doors that had been previously unaccessible.
In the SDK, you'll find things like some sample code, the Android Debug Bridge (ADB), and the Android Virtual Device (AVD). But, just like many developer programs out there, you'll need to sign up an account with Barnes and Noble to be able to download the SDK "officially." You can check out the Barnes & Noble NOOK developer site, right here.
