As it appears in the recent CVS activity, the team behind the superb Rockbox are working on supporting iPod Color/Photo and iPod Nano. The work is still initial, and I have no knowledge if the work is meant for testing or if there is an actual plan.
Rockbox on iPod would most probably mean Ogg Vorbis, mpc, ac3, Wavepack and flac support on iPod (along with Apple Lossless, mp3 and aac). The only downside I can think of is that Rockbox have no DRM support, and that music from iTunes Music Store cannot be played.
Although I will never trade my iRiver H140, I find this exciting news.
