Not to mention, if it's valuable enough, there will probably be coffee production specifically to produce biodiesel that never gets made into consumer coffee. Similar to the vast amount of corn grown strictly for ethanol production.

I suspect coffee was chosen because there are a lot of wasted coffee grounds. There likely isn't anything specifically about coffee that is needed here, you could probably use any number of similar substrates that are cheaper to grow

Oh, I agree, but even corn for ethanol was only supposed to be using waste products and not corn grown for ethanol, but once you give the industry an inch to grab onto, they'll take all they can get.

Very true. The issue there isn't the tech, it's the economic system....
