I have always just downloaded the .mp3 file and put it on the empeg (the same way I have been for years before anyone came up with "podcast") I don't listen to that many that it's worth doing some automated thing.

You can just have ipodder download to a folder then just copy the one folder to the empeg. I doubt it would ever be like the ipod where you just plug it in a all the files are uploaded with no intervention.
