A question for the general public - what sort of stuff do you have on your desktop and needs some sort of conversion to make convenient on your NIT ? Stuff I have so far (most of it already implemented):

doc, docx, odt, sxw -> pdf or html
avi/mov/dvd -> scaled/recompressed avi
ftp or streamed video (youtube incl) -> avi
streamed audio -> mp3
tv tuner -> avi
flac, ogg -> mp3
oversize jpg/tif/raw -> display sized jpg

Anything you fancy and I don't have here ? Don't be shy !
