Great
I have a jailbroken KT4 that I am willing to help develop a jailbreak on.
The kindle has gdbserver so i can debug stackdumpd to figure what need to be passed to it.
For distribution it might be a good idea to package it as a self contained webpage that the user can access from the browser via `file:///mnt/us/webpage.html`
this is not any worse than some of the other jailbreaks that are also RCE.
