Think about it. Get an iPod and install this to it.
It might be trivial for a programmer to add this to your custom iPod.
I am looking for a MP3 player that I can delete the mp3 after I listen to them. I am only using this for podcast with Podcastready software and I listen to about 7 hours worth a day and I don't want to try to remember what I listened to to delete them when I get home. I have been using a Creative Zen Micro and a Creative MuVo since those are the only ones I have found that can do what I am looking for and wish to upgrade to something newer.
