Funny that you start and end with similar concepts (mostly a matter of wavelenght after all...)
Make Adama proud: Connect your Things wisely, cadet
Last time I explored the concept of geofencing, and how low-power technologies are used both to create "virtual walls" and to create beacons. This time, I’m going to take a look at the individual technologies that Internet of Things (IoT) devices will use to communicate for the next several years. Infrared Infrared beacons …

Z-Wave?
You missed Z-Wave, but to be honest it has pretty much the same properties and problems as ZigBee.
This sort of thing could be done more securely but the big problem is that most if not all of the controller or stand-alone systems are managed via someone else's server on the Internet (I'm refusing to say the 'C' word). My security and privacy should be solely under my control, not mine and someone else's.
I'm currently playing with openhab - a bit rough around the edges but looks like it could be moulded into something pretty good.

What's already out there
Let's not forget narrowband radio for linking large numbers of low data rate sensors and controllers (e.g. streetlight control and monitoring over Ultra Narrowband radio links which is already widely deployed in the UK). This doesn't fit with the purist version of IoT in which every device has its own IP protocol stack and connects directly to the Internet but that doesn't mean it's not a valid way to do IoT for devices that have modest data needs and limited available bandwidth.

We need a scale of uselessness
We need a proper numeric scale of uselessness here - following on from the article can I suggest the "Admiral Adama Index"
AAI10 = truly and utterly and completely useless
AAI 5 = really useless
AAI 1 = almost not quite useless but you are never getting any of these things in my home thanks all the same

Re: Admiral Adama
Adama was the commander of the only remaining Battlestar warship. It was used in a previous war with the 'Cylons' (a robot like race) and Galactica was due to be moth-balled as a museum piece. As such it was not retro-fitted with up to date kit that was networked together and with a central mainframe for efficiency. Adama, as a veteran himself distrusted such intercommunication between devices. His distrust was dismissed as being anachronistic and paranoid.
Sure enough, the Cylons returned, compromised the mainframe and pretty much instantly disabled/destroyed the entire defence system apart from Galactica.

Re: you probably should watch that one
Sadly I can't suspend disbelief for long enough to watch any TV series of a fictional narrative nature. I can just about manage a standalone film but if I have to either come back next week for the next bit or binge on an entire series at once then there's no chance. That's for everything - not just space opera. But others are free to enjoy whatever shows they like without condemnation from me.

Re: Admiral Adama
I turned on my TV one Saturday afternoon a few years ago, to see 5 women doing roller-disco in silver miniskirts to some sort of synthesiser bebop. Before it cut to Starbuck (or Face out of the A-Team depending on your age) winning another hand of space-poker.
Through my laughter I reflected that nothing dates as fast as peoples' ideas of the future.
I suspect if I went back and watched it now, the original Battlestar Galactica would look really crap. I loved it when I was a kid, but then I still remember the disappointment of getting a DVD of Blakes 7, ten years ago.
In my opinion, the first series of the BSG remake is absolutely brilliant TV. Really well made, well written and just well done in general. But once they go into series 2 I thought it started to go downhill, and I stopped watching sometime in early series 3. Other opinions are of course available, but I'd rate that first series alongside anything else I've seen, sci-fi or otherwise.

Re: Admiral Adama
The first season was really a re-make of the original. Every episode has some kind of connection to part of the original series, either by borrowing characters, scenes or entire plotlines.
Season two is when they couldn't believe that they hadn't been cancelled yet and needed to start writing their own stories. It didn't go so well.

Re: Admiral Adama
I think that he can explain in his own words.
"Let me explain something to you. Many good men and women lost their lives aboard this ship because someone wanted a faster computer to make life easier. I'm sorry that I'm inconveniencing you or the teachers, but I will not allow a networked computerized system to be placed on this ship while I'm in command. Is that clear?"

What about good ol' wifi though?
With wifi SoC devices like ESP8266 and Ti's CC3100 putting together battery powered IoT service seems easier than ever and the advantage of easier 'home network' integration.
I'm using both ESP and Bluetooth modules with Arduinos at the moment but could easily see the ESP taking over all the Arduino work for most remote sensing/activation requirements.

Zigbee...
there are people selling Zigbee gear that think it would be a good idea to have Zigbee home security systems
Such home security systems already exist - I used to work for a company that developed them.
Mesh networking is not the problem you believe it to be - just because your items form into a meshed PAN, that doesn't mean that anyone else's can join in too. There is authentication and encryption within the protocol...

Wasn't there a hack against various bits of networking kit that has LEDs connected directly to the TX/RX lines. If I remember correctly "attackers" were able to pull data from another building via a telescope & some electronic trickery.
Anyone who tells you; Oh no don't worry, it's very short range should be treated with snide derision.
Hint Telescopes and Antennas are effectively the same thing

Perhaps more accurately, a group of researchers demonstrated that they were able to reproduce the data stream with good accuracy by observing a modem's Tx/Rx LEDs. (I think it was a late-generation async POTS modem, so probably V.34 or V.90 with V.42bis.) If memory serves, they did demonstrate that it could be done with some reliability through a window and over some distance. I can't find the paper now, though.
