I know this may be a little unethical business wise but couldn't Jobs just say to Disney: "You want to keep distributing Pixar, right?" It's a win win. Disney makes revenue off of sales through the iTunes/Video/Media Store and Steve agrees to their distribution of Pixar films. And I am sure he would also try to lock up some sort of exclusivity to keep out MS/Netflix/ect.
On the other hand, distribution rights for Pixar films would make a good bargaining chip to the scads of other companies with large back catalogs too.
Or maybe I am being a little optimistic. 😉
