Your talk about efficiency is a bit of a strawman argument. I'm talking about suspension performance.
There are more components/factors that impact efficiency than drivetrain alone. Rulezman (Italian suspension guru) is pretty keen on riding with less aggressive tires as they save you so much time on the climb and have little impact on descent.
FartyMarty is right about about Sram and Shimano not wanting to bring out gearboxes. They have invested a ton of money in maintaining the status quot.
For the record, I'm cool with moving the cassette and derailleur into the front triangle like the Honda downhill bike style or Trinity.
