Here's a completely different approach, chain drive in the back, shaft drive in the front:

I'm skeptical that any of this actually leads to increased traction, but I don't know how much you lose due to the efficiency loss in the more complex transmission. However, I've got to think this woman must be seeing a real gain or she wouldn't be using these bikes for her incredible cross-continental rides, especially as she has bad knees.
