I believe Nikon uses RF slave flash control for many of their DSLRs.
Too bad Canon and Olympus didn't also. I haven't tried a high end
optical slave but neither the Wein nor the cheap chinese optical
slaves are nearly as reliable as RF.
The multi-sync command module of the Olympus IS series immediately
came to mind, but I doubt anything similar will be built for the
E-cameras
