If farmers were willing to accept bitcoin, or even not bitcoin but cash, but someone like I or some other highly intelligent person
were to organize coffee farmers and the coffee bean roaster in say, America. They catch is that the buyer and the seller need to be willing to use bitcoin for the transaction.
Perhaps the seller ships the product up front to establish the relationship, all accounts get active management to breed strong relationships. And connect in the best way possible coffee beans from the country of origin to the the larger consumer worlds.
Coffee is a unique product, as it is largely consumed and prepped far outside the region it was grown in. It is the most common beverage in the world. 2nd being Tea 3rd being beer. And America is in the midst of a coffee roasting and 'light roast' boom. The retail side of the gourmet artisan stuff things is becoming a very big and highly profitable area of the economy.
The thorny issue arises by trying to create a true peer 2 peer marketplace when there is a large knowledge gap on both sides of the border. One country I was looking at on a map for gigglez, is Costa Rica.
I would have to act as a middle man, and perhaps even escrows would need to get involved, at least initially, with goal of transitioning over the next decade or so to a true p2p marketplace, in which my service wouldn't be needed at all. Places like openbazaar are not going to work, at least not any time soon with newness of it and bitcoin. I am not bashing open bazaar, but rather mentioning it would be very difficult to get behind a platform like that.
In the short term this could create a niche for me to profit from, while also getting top dollar for the farmer, and the best price for the buyer. Perhaps unroasted coffee beans are already incredibly inexpensive when purchased in bulk, and this entire idea is unworkable even if it were not for the knowledge gaps in the potential participants using bitcoin.
