Is it RAND and is it a standard
The obvious questions: Will intel license it under RAND terms and will make a proper standard out of it which other vendors can interop to and build to.
None of the news so far say a word.
In any case, if this gets standardised and if someone does some silicon for a switch fabric for this it will have a number of interesting non-apply, non-display applications in the supercomputing arena. PCI-Express to a distance of 100m makes for a very tasty interconnect :)
