Not really. I don't see discotheques or bars buying it. They generally buy the cheapest plastic glass they can find for the former and the later have drink companies offering them free glasses. As for private parties, where your cup is likely to be lost or broken, people won't bring this expensive cups with them.

To me it's more, "lets surf on the Internet of Things". As already said, I don't see the need. Maybe if one day it become as cheap as normal cups. But not now.

Not I saying roofies are not a problem. Just that is not a solution, IMHO.
