Much like printer makers barring cheap ink, Keurig is using elaborate methods to block third-party coffee pods; its upcoming Keurig 2.0 machine will have cameras that read tags and limit you to official brews. Think of it as K-cup copy protection. Unfortunately for the company, those added measures may be for naught. TreeHouse Foods, which sued Keurig for allegedly abusing a monopoly with its 2.0 system, now estimates that it should take just a "matter of months" to replicate the K-cup technology. The discovery should keep TreeHouse selling unofficial pods that cost significantly less than Keurig's, and it could also thwart similar protection schemes in other companies' coffee makers.
