"What are the pluses:
1. Not life of the belt. That sounds like about a wash to me

YOu have to go by more than the belt, it's altogether whether the system wears better, the chain grinds the other parts and the whole system wears out. Which in turn grinds on the belt. 8000 miles is pretty good out of a chain. But either way it would have to be more than just a cost issue. This is going to be a very costly bike, and an extremly costly trip if we are stretching out over multi year distances. It's going to come down to which product one prefers.

2. Not repairability. If it breaks you need to have a spare.

The fact it weighed, what 9 times less would be huge.

3. Silence. Maybe, but so what if you are going to use a noisy Rohloff.

Well at least when you aren't in the crossover gears it might be tolerable.

4. Efficiency. Not even in their own tests.

This all depends on more than tests, chains are nasty afeter a few hundred miles and never roll like they did on day, one. This will be better or worse.

5. Cool factor. Maybe if that floats your boat.
6. Not cost, especially if you have to go to a Rohloff, which would seem to be the only way to get a reasonable range of gears.

Come on, and pulleys are expensive if you have to trade your rohloff for a derailleur system to use them.

7. Not the ability to pick and choose ratios it seems to come in only one.

Could be big problem, but if it is worth it, it will pick up.

8. Not availability of spare parts. There is only one source at this point.

QBP means everyone can have them if they actually make them in quantity.

9. Not ease of fitting it to an existing frame. You pretty much have to go to some weird frame or go custom at this point in time.

Right, big problem, but you can say that about any inovation. It is either going to sell itself off the showroom or not. Think MTBs. not that long ago they were just an idea. If it is perceived as useful frames can be changed easily.
