Apple specified constraints on the solution. That is not the same as developing it. Neither has Intel put this in front of a standards body either.
They are trying to stick some aspect of it in front of the USB body but this isn't necessarily the right standard.
Apple (and Intel) could ship something before reaching a significant consensus from the industry, but long term that may end up hurting as much as helping.
Remember, for this to be useful and widespread it has to be someone other than Apple and Intel that has working offerings. There were some vendors who said Firewire was cool too .... until they have been drifting away. ( maybe for this. )
Some of Light Peak seems half baked (e.g, USB like power over the same cable. ) Frankly have trouble with the Light Peak distance claims ( 100 meters) http://en.wikipedia.org/wiki/Light_Peak and providing power over those kinds of distances. Which either gets you short distance with power Light Peak and pure optical Light Peak or dropping of some of the "yeah and that too" claims.
Likewise all the of multi/demultiplexing of putting random stuff out of the lab on the same wire.
Mac Pro with USB 3 might be more likely. Or that Apple is going to by-pass it (like eSATA).
Apple could bypass USB3...
It's seems the Intel side of Light peak came out of the sidelined usb3 optical spec. Free of USB it could then take on board ideas it couldn't before.
Also thinking it adds to the work of UWB which also able to carry lots of data stream types sort of natively but with light as the carrier not radio.
The problem is it's all very short on details.
Yup. Lightpeak is at this point a technology demonstration. It's nowhere close to production if they're having to modify existing motherboards to show it off.
The Mac pro is intel's tech demo machine of choice.
