From Dave Winer's post, 'Yahoo game-changers for 2006':
P2P webcasting. I wrote about this vaguely the other day, and no one apparently understood what I meant by Skype for webcasting. Come on guys, it’s pretty simple. Suppose we’re having a conversation, and I decide “Wow, this would be great for Scripting News, let’s do a webcast of this right now.” So I whip out my laptop, get onto the net (there’s wifi everywhere of course, heh) and launch my Yahoo Webcaster desktop app for the Mac. I choose New Webcast from the File menu. A window opens. There’s a button that says “Copy URL to clipboard.” I click it. Go over to my outliner, paste it into a post on Scripting News. “Tune into this webcast I’m about to do with Bull Mancuso about intellectual property and organized crime.” I highlight the word webcast and click on Add Link. Save. Then I go back to the Yahoo app and click Start. We talk for ten minutes, all the while people tune into the stream, which is managed via a realtime BitTorrent-like P2P connection. And of course when it’s all done it’s automatically archived to an MP3 and included in my RSS 2.0 feed for people who subscribe. If you’ve ever done a webcast, you know how much better this would be. And it’s ready to go, we know how to do all the bits.
And Kevin Marks adds in his comment to Dave's post:
Dave, have a look at GarageBand 3 and iChat. You set up your n-way conversation in iChat, you hit record in GarageBand, and it creates a multitrack recording of it for you with the speakers labelled. You can trim it, adjust levels ad effect, or just dump it out to mp3 straight away.
We should get right down to exploring and using these methods: homegrown webcasting has huge potential for schools and education.
I said wherever you’re doing something to make another industry happy at the expense of users, switch polarity, immediately, and get on the side of the users. That in itself is the biggest game-change possible.
