Even if they print an entire logo in the ink, someone could sell some kind of reusable sticker with that special-ink-logo and just stick it onto the non-Keurig cups during use. When finished with 1 cup, remove sticker and stick it on to a different cup.

I don't see why they even bother trying to lock down their machines TBH as it can't be done well without significantly increasing the cost of the machine or cups (or inconveniencing existing customers).

I have a Keurig (non-DRM) and buy mostly Keurig branded cups anyway but if I had to buy one of these "2.0" machines with DRM, I'd just not buy a Keurig machine.

Or put the sticker over the sensor. Or hotwire the sensor (caution: voids your warranty).
