Sorry.  I didn't mean to imply that it had failed for technical reasons,
but I came away from the discussion at the RNG workshop with the idea that
it had failed for financial reasons--it cost something nonegligible to
produce, but didn't raise the price of the final product.  I didn't
realize that it was a problem with manufacturing process changes.  (Was
that where most of the cost was?)
