In fact, my company is an OEM that sells expensive hardware/software setups, and this is what we use to enable/disable software features. If it didn't work, we'd potentially lose hundreds of thousands of dollars.

Edit: Well, I guess I do see it. It might put people off of buying the game in the first place. But, I wouldn't think it would put off as many users as it would save them in piracy.
