Light Peak in embedded systems

Light Peak is Intel's new optical interconnect system, using on-chip laser/receivers (up to 30x cheaper than existing laser technology, they say, and smaller). It's coming out at the end of the year (2010). It works.

Now, what is surprising is that there seems to be _absolutely_ no buzz about this in the embedded world. Why? Isn't this a perfect technology.

- optical so no ground loops and/or electromagnetic disturbance
- good latency (I believe, did not find figures)
- multiple protocols running simultaneously (and quality-of-service handling)
- up to 100m cabling distance without repeaters

We'll be using this for a PRT system's internal communications.

Here's a collection of the best links I found:
