Berg, Multiplex and FMA offer this technology in Small footprint RX's currently and its widely utilized and accepted in the electric world.
They're no longer limited to small electrics and park-fliers though.
I'm using these receivers in much larger planes (.90-sized) where they outperform conventional PPM and in some cases even PCM receivers. It's quite surprising just how good some of these smart receivers are.
As I often say (:-), I can't understand why people continue to buy "dumb" FM/PPM receivers when these smarter alternatives are available for the same (or sometimes even less) money.
