Some music junkies have begun using the PC VOIP product, Skype, as a broadcasting platform. It's like podcasting in some ways, so it's being called, "Skypecasting." Did anybody forsee Skype, a telephony app, being used as a media distribution platform? Not really. But it's a great illustration of what can happen when you release a new platform and don't get in its way. Skype is taking a hands-off approach to the development of apps like this. Good for them.
Update 4/1/05: Per feedback post, Bill Campbell of SkypeJournal claims dibs on the concept, and published instructions for Skypecasting with Stuart Henshall in December of 2004.
