I _believe_ that the last I read on that was that the scientific communuty
was still trying to verify that what was apparent is what really happened.

In another vein, I saw a presentation some 10 years ago (or better) on a
different version of "computing with light".  The IC chips didn't
have wire leads attached, other than power and ground leads.  Where the
pins would have been were micro-LEDs.  The chips didn't have to be soldered
to boards, they were just stacked adjacent to each other and
"transmitted" their data to the next chip.  They could be stacked
vertically as well as horizontally, no circuit board, no stray
capacitances, and it was reported to have very high MHz (or GHz?).  The
whole thing was a little cube about the size of three cigarette packs
stacked flat.  Never saw any followup, and never heard any more about it.


     Good luck...  M.
