I am surprised very much, that such a revolutionary new technology has such a small interest in this forum (and whole designers community?). First it should be much more reliable, because it is completely silicon and not hybrid. Second it is very fast.
Some years ago I have designed an active mirror control system for a MAGIC Gamma-Ray telescope. There are used about 200 optocouplers (inside the MAXIM MAX1480 IC) and during 4 years we have 5 LED faults, so the optocouplers are the bottleneck for the whole system reliability. Now I make an experiments with the Analog Devices ADM2483 RS485 iCouler interface chips and they work very good. I am going to replace all optocouplers with iCouple chips in the new MAGC-II telscope design, but before I want to know colleagues opinions.
