ok, here it is, i just took the apk from my phone, i don't have access to the source at the moment.
it's a really basic application, it 'supports' PW(1?, not tested 2) kindle 4 NT, i forget if that means it works with k3 also..
for the PW, you either need xdotool (attached) in the bin folder of the usbnetwork folder of the kindle, or in a folder called 'bin' of the kindle. i forget which directory i am looking in it for... i can have a look later.
you can use a password, or a private key to log in.
with PW, you can change the light intensity, also turning it off if the slider is at the lowest value i think.
the reading direction can be changed, since with books that read 'backwards', as in japanese etc... so the forward button will still go to the next page.
there is an option to force the screen of the android app on, since when the screen would time out and turn off, the connection would break, i think...
honestly, it's been a while since i have used my kindle, let alone this application. from what i remembers, sometimes it disconnects after a while, i can simply call a reconnect function and it all works fine after that... maybe i was doing some connection stuff wrong, i've never worked with ssh stuff before, and i am by no means a good java/android programmer.
i saw some link to some other guy's work, i'll have a look at his code and see if i am doing anything 'wrong'

i think the volume up and down buttons control the page turning

i forget which android keyboard buttons i check for, that could be triggered with a bluetooth controller and bluezime, i just wanted to put this up here just so it's here, i never meant to not share it, when i have a bit more free time i can update it and give it a better interface etc...
credits for the people on irc, twobob etc, he sent me xdotool i think, i'm not sure if he compiled it or whatever, and to the jsch java ssh library, which i did not enjoy the documentation for, but was thankful for it since i wouldn't have been able to do this without it.
sorry for my vagueness, and no screenshots etc, but at least it's free right
