I noticed iFeedPod, which seems to be an RSS Reader for the iPod. It sounds like it syncs the feed items from your computer to the iPod for "offline" reading. I really like the idea, but the implementation is Mac-only and only free as in beer (not free as in speech) as far as I can tell.
Does anybody know of a similar software which runs on Linux and is Free Software? Do I have to implement it from scratch?
