According to the Guardian Apple is
on something called 'QuickTime 2 RSS,' which will allow someone (in this case a teacher) to record a
lecture and then have it automatically encoded for playback on a video enabled iPod and seeded to an RSS feed, which
would automatically be populated on the iTunes Music Store. The best part of this? It would be free, you just need to
buy the camera and the Mac to run it on.
Unless I miss my guess, this will be an addition to QuickTime
Broadcaster, though I have been wrong before.
And a word of warning, this article is a 'Guardian
Advertisement Feature,' so make of it what you will.
