Here's an article from Ars Technica that goes into some detail about the new Keurig Cups and their proposed product revision that locks their machines and pods to their proprietary technology.

There article is worth a read, simply given the state of the mainstream coffee business and where its going. Music, and increasingly movies and books demonstrate how useless Digital Rights Management protections really are. Building it into coffee pods its phenomenally dumb.
With the increasing droughts in coffee producing regions, and the rising price of coffee, we don't need anything else to drive up the price of our favorite fix.
