scripting the iPod?

Any chance to script applications on the iPod or the iPod itself?

i’ve found an interesting code somewhere. (sorry, i do not remember, where). Would be nice to implement it, if possible. (its designed for pdf-readers, its an autoscroll feature)
Unfortunately its not applescript- and i doubt apple will add applescript capabilities for the ipod (4th gen)

Sorry if this post is a bit offtopic.
