ipodder Juice
I think it would be great to have Juice (ipodder.sourceforge.net) converted to a portable app. I installed the program to my hard drive, then copied the folder to my flash drive and the software does run, but the settings are not retained (feeds, target folder, etc.) I think someone could do this fairly easily, but I'm not the one. I don't have a clue what to do. It is open-source, so modification shouldn't be a problem.
