Fermented Green Papaya - "Atchara"

I am wondering if anyone has tried "Atchara" (fermented green papaya) or raw coconut water vinegar? I came across these on tropical traditions' website.

Looks pretty interesting - hope someone has tried it! Their website also has some good commentary on raw coconut and that fact that it isn't really raw. You can read it under the FAQ section on their homepage. Guess I will just have to buy whole coconuts!
