> universe of media distribution that happens via an open protocol that is not controlled by any one company
What is this protocol that you speak of? Searching "podcast protocol" leads to absolutely no useful links on the subject. Podcasts in my experience are distributed in one of three ways:
* Download links on a web page
* Embedded streaming links on a web page
* An RSS feed
That last (RSS) could be considered a "protocol" of sorts, I suppose. At the very least it's what I would expect a podcast app to support. But you then go on to refer to RSS as a separate entity from your "podcast protocol", so I'm back to being confused as to what you might be talking about. What is this open protocol that is intrinsic to your definition of 'podcast'?
