I have read that at least one Nepenthes nursery in southeast Asia grows all their plants in it, though they are able to source cleaner coir. Others have experimented with it and it seems that most people are put off by the amount of work involved - though there are cleaner coir products coming on the market now.
Yes, Robert Cantley (Borneo Exotics) grows his nepenthes mostly in Coconut coir, but they are collected far inland.
