Sorry to interject in your fine mudslinging back and forth, but from what I see, the crux of this whole discussion is this:
1) In Dune, the worms (vector) do not produce the spice (we all agree here).
2a) In KJA's books, the worms produce the spice (the OH reading of KJAs dictations).
2b) In KJA's books, spice works just like in Dune, and KJA has a certain propensity for using "sandworm" to refer to all stages of the sandworm lifecycle (the NuDune view).
The whole thing comes down to how you read stuff like this 8got those from Sandchiggers posts):
Using carefully mapped models from sandtrout chromosomes, Waff knew that these creatures had the same internal metabolic reactions as a traditional sandworm.
Therefore, they should still produce spice, but Waff didn't know what kind of spice, or how it would be harvested. He stepped back, interlocking his grayish fingers.
As if connected directly with Monarch's nervous system, Sheeana could see through the eyeless worm to its companions beneath the sand. Working together, the seven sandworms were forming small veins of spice in the cargo hold.
The last one is obvious, of course. There are seven sandworms, they are producing spice. Unless you are claiming that Sheeana is refering to them playing with the spice like children on the beach,
forming small veins for no apparent reason?
Anyway, instead of all the shouting and back and forth what an organism, life vector, etc. is - I would much rather hear some way of reading that last quote to mean that the sandworms were not, in fact, producing small veins of spice. I am not holding my breath, though.
