Podchains is a web-based app that allows users to bookmark “already-online” media of any kind and then construct an RSS feed around the bookmarked items, to which any number of persons can subscribe to with iTunes or any other Podcatcher. The main listed applications are just for fun, that is: to share the stuff you enjoy with the people around you.
Another cool market niche is for those people who manage podcasts and publish them on a regular basis, so all they have to do is upload/bookmark the stuff, and the site will do all the letting know by itself. However, what I reckon is the most profitable area is for work teams that organize their task on an alert basis, that is: a group of people that needs to know when something is published and available, and have it hosted in a dependable server that don’t crashes regularly, like radio correspondents or music performers who play on a band.
