Back on the 21st of January when Amazon announced that it would release its Kindle Development Kit
, A/K/A KDK, we heard it would begin rolling out in limited beta this month, with a wait list of people getting access to the kit as space was available. Well, that moment has arrived, and you can now sign up to receive said KDK. Our tipster wasn't able to get the software in hand yet, but we'll keep on the lookout for it. Hit the read link to sign up, and to check out Amazon's FAQ, as well.
