Here's a Honda press-release on it. It is entirely possible that the S2000 system is something different, but I have a feeling that this is just a combination of an EPAS system that does something similar, in addition to varying weight.
I agree with you on the lack of mechanical linkage. Nissan has some system that retains the driveshaft for times when the steer-by-wire is malfunctioning, but I have a feeling that by the time it's malfunctioning (10 years on), the mechanical fall-back mechanism will likely be faulty too.
