I kinda think that ship has sailed.
It used to be, ankle monitors with transdermal alcohol sensors and GPS on them were the rage. About 10 years ago. Keeping the batteries charged and such is problematic. The anklets themselves are not easily defeated, but have technical drawbacks as does any device designed to forcibly restrict addictive behavior.
The new trend is hand held portable breath tests with GPS and cellular backhaul. The person subject to monitoring is required to have it with them at all times, and it makes somewhat random calls to require a sample. Many of those calls come in the hours past midnight or shortly thereafter.
The trick of the show is the device has facial recognition built into it. So as the subject is providing the sample, the device is not only monitoring the identity of the user, it's transmitting the BAC and the location to a monitoring center.
Any violation triggers a call back response to the monitoring agency, which ends in detention by officers who are more than happy to rack up double OT to come out and do it off hours.
The contracts for these devices, and the agencies that use them change at a glacial pace. The profit margins are pretty slim, and the protocols used are semi proprietary.
The ROI on trying to break into this market would be too slim for Apple to have any interest in it, along with the bad PR for anything CJ related these days.
