You are misunderstanding what "911-only" means. Any cell phone that has no arrangement with a cell phone provider can still dial 911 and be connected. There is nothing special about the phone, it is an ordinary, unmodified phone that no one is paying for service on.

In large cities only taxicabs have the right to cruise for passengers hailing them on the street. There is a different class of vehicles (called "black cars" in New York, "limos" in Boston) that respond to telephone requests for service. This just creates a 3rd category that responds to requests over IP (is there an RFC for this?) and has still different rules. Only taxicab medallions are limited in quantity and valuable in trade. Anyone can own a taxicab medallion- there are NO qualifications. However, that doesn't give the person the right to actually drive the cab. The medallion gives them the right to appoint a driver. The driver must also be licensed - there are no quantitative limits on the number of persons licensed to drive a taxicab. This puts the drivers in a poor position to bargain, and all the profits go to the medallion owner.

Will there be a standard receptacle for EVs to plug in to? Or will each manufacturer have his own "refueling" stops?

I wonder how much malware is included in the download if you uncheck all the boxes - I wouldn't assume that would help, though it might in some cases. I'd also be interested in how much of the malware was proof against removal. Obviously any malware that re-installs itself after removal is much worse than malware that permits uninstallation. My own view is that automatic reinstalling is a felony under federal law regulating computer crime, but apparently the Justice Department doesn't care.

They might forgo calling it medical equipment. If they call it a toy, they don't have to have FDA approval. It isn't invasive or anything and kids might have fun with it - as good as x-ray specs.

The current system is sufficient to purpose, but few people know how it works. Here is how: The lock stores a list of 10,000 keycodes in random order. The front desk has the same list. At installation (or reset) the lock will open for any of the first couple of codes on the list. Once a code is used, any code earlier on the list is no longer valid but the next few become valid. This way the front desk can issue a new code that will be accepted, without communicating with the lock itself. My own view is that if the new system allows one-hend entry, that is a big win.

Our problem with the Supermicro IPMI units is that they eventually crash. Once down, we don't know any way to reboot them other than to power cycle the machine, which imposes downtime on the users. So we leave the IPMI down. This is Linux, perhaps it is different in some other OS.
