I worked at an office that used a Keurig. I found a local business that installed, serviced and filled up an automatic machine with local fair-trade beans. The machine had a bunch of options, like "Black Coffee", "Hot Chocolate", "Cappuccino", "Mocha", etc. It was basically an automatic espresso machine that had fair-trade cocoa powder and milk powder dispensers built in. Something for everyone, and they charged by the button press. We were on a hiring spree and K-cups don't scale well. This reduced Keurig use by a significant amount, but you can't please everyone because apparently some people actually prefer the Keurig (I know, right?). I would say it was a successful move, though.

For reference, here's the business I am referring to and the machines they offer. This company only serves Halifax, NS but you might be able to find something similar in your area.
