PW2 Want to rotate through screen savers automatically

Hi,
I have a jailbroken PW2 with the screen saver hack working great. I wanted to rotate through the screen savers periodically though, since I want to show quotes on it and hang it on the wall. So I searched around today and saw a thread mentioning that the screen saver only changes when you timeout or push the button to lock the kindle PW2. So I have some questions:

1) could I write a python script to do this rotation?
2) or would it be faster to learn the screen saver hack and try to add periodic rotation in the binary there?
3) Do I need ssh and usbnet to run python scripts on the PW2?

Thanks for any tips or ideas!
