Jon Udell pointed me here. You can listen to Stanford lectures -- but only on iTunes. I gather Apple is cosponsoring the project. Jon is rightly concerned about the iTunes lockin; he connects it to the DRM plague. I'm confident Microsoft will sponsor something similar -- with a lock-in to Windows Media Player.
In fairness though the lock-in part is not really DRM, it's the same old technique that made Microsoft the most dominant corporation in the past century. Apple's very good at it too, just not as clever as Microsoft.
