Okay so I know its not exactly 100% useful, but I made this simple-ish thing that allows you to run an ssh server on your kindle,

it is an wrapper with some important steps built into the thing,
extract the `sshd-lite` folder to the `extensions` on your Kindle,
select `SSHD-LITE` in KUAL and click `Install/Reinstall` BEFORE clicking start, the kindle uses an bare bones linux system and the install script creates a few symlinks, modifies iptables to allow ssh, and adds an upstart config script.
Unfortunately sftp does not work with the current sshd I am utilizing (

I chose this ssh server because it is an standalone, STATICALLY LINKED binary. this means that its only dependencies is that the system uses a linux kernel, and the kernel is the correct architecture (armv7 in this case, however I am using the armv6 binary for safety)
