Reverse Engineering iPod Games

Apple does not seem to have an iPod SDK available to the public, and from their response to Ben Sinclair's request (link), they are not planning to release such an SDK soon. Some developers have decided to reverse engineer iPod games they have downloaded through iTunes as an alternative, using this wiki to share knowledge. They emphasize that their goal is not to crack Apple's DRM, but at this point it is not clear to me (and probably to them) whether what these people are doing is unlawful according to the DMCA. We can only hope that Apple will not try to take any action against them and/or will release an SDK.
