anybody know if this is possible or if it's been done before? i was thinking it might be worthwhile if i could get an ipod cheap from like freeipods.com or something and turn it into an external hard drive for storage, plus it's innocuous: nobody would suspect you were storing anything on it except mp3 files. it would be like, you know when you get a real thick book and cut the middle of all the pages out and then glue the pages together and hide stuff in it on a bookshelf
