We don't know, because Apple never said another thing about FaceTime being submitted as an open protocol. Someone might even think they made the empty promise just so they wouldn't get flack about another proprietary chat service. But who knows... Apple should have addressed it one way or another.
Just as I suspected, this point is rationalized away with speculation. He said:
“And we’re going to take it all the way. We’re going to the standards bodies, starting tomorrow, and we’re going to make FaceTime an open industry standard.”
The reason this rings so hallow is because it is so outside the MO of Apple. If Apple creates something they think is really great (and customers do too) it becomes part of what sets Apple apart. Apple doesn't license their technology, they use it as a key differentiator. The only real contribution Apple has made, in my mind, to open standards is webkit; and they built that on top of KHTML so I'm not sure they really had a choice.
