I'm the guy that has the keys to the kingdom when it comes to thermostats. You absolutely have to keep them locked up - nobody knows how the hell to use them. In our building, there are many zones, and almost none of them work properly even when the stats ARE programmed properly. The situation is so bad that the hope of programming the systems to save energy while the building sits unoccupied has been completely abandoned. It's a huge clusterf*ck, and the upper management doesn't seem interested in fixing the actual problem.

I work in radio broadcast engineering. As much as most of the folks in the industry would like to move forward with other more "modern" communications for real-time audio, the solutions for audio over IP in terms of using the public internet and high-speed wireless carriers leave much to be desired. Sadly, it's no fault of the manufacturers as far as I can tell. For real-time traffic, the public internet is a very hostile place. A T1 or ISDN line (especially PtP installations) is old school and expensive for bulk data, but is sometimes the only solution when you need the rock-solid reliability required for broadcast applications. 4G comes close for wireless (nice quick pings compared to 3G), but sadly it falls on its face when a big crowd is around like major sports events, etc. Walk into any tech center in a large stadium, and you'll find all sorts of copper connections. They exist solely for the broadcasters, because we can't afford to let them go. With more and more providers abandoning the technology, many of us are forced to use circuits that are already in place. The cost of installation has increased significantly, and in many cases is no longer available depending on the market. Definitely a problem for small specialized industries like mine.
