Peter has a bunch of Leo's podcasts that he's downloaded over the years. But now the shows are all out of order. Leo says that advertiser based technology has forced a change in how they name their podcast files. The files are run through a service called Megaphone, which then triggers an ad at an appropriate spot based on what your interests are. As such, the file is named differently for each downloader. But there is a solution. You can get an mp3 renamer that can change the file name based on the file metadata.
Juliette wonders if you can create a cellphone megaphone app that can turn a cellphone into a megaphone. Leo says that's an interesting idea. There are third party add on hardware options that could do that.
