Kindle Voyage/Kindle 6 Jailbreaks?

In September Amazon announced the Kindle Voyage and 'new' Kindle (Wikipedia calls it Kindle 6, Amazon's source code notice calls it the Kindle 7th Generation). Is there any effort being made to jailbreak them? If so, what's its status? Any way I can help or be pointed in the right direction to start a jailbreaking effort? I have a lot of experience with C/Linux and a Jailbroken Kindle 4NT, but I wouldn't know where to start jailbreaking a new device.

Thanks! The stuff everyone here does is amazing and I'm excited to be a part of it!
