I also have to wonder how much the spectrum grab will affect shortwave/HAM radio operations?
I know this is pretty much a non-issue for most folks (including me, at least up until now -- I have a low-cost "emergency" weather radio on the way that also includes shortwave band, so I might listen in for the first time ever), but it's my understanding that throughout the decades, time and again in certain serious tragedies and emergencies, amateur HAM radio operators have quite often been the SOLE source of information out of ravaged areas to communicate with outside help, and so forth, so I think their continued existence plays a small, but vital role in the overall scheme of things.
Once, years ago, when I was the assistant editor for a weekly newspaper, I was invited out to a "mock tragedy" event the local HAM club held every year or so... They'd set up tents at a local park and set up their radios under them, and have contests to see which operator could make the most contacts and transmit the most information -- all via Morse Code -- in a set amount of time, to other HAM operators around the world. Their instructions were, I think, to find one operator just by scanning, transmit a message and get confirmation back, then search until they found another and repeat.
I know even the military has quit teaching Morse Code to recruits and cadets (a mistake, I believe, since I think it's still something that can, and does, come in useful when there's no other way to get a message out -- like when someone is trapped under rubble but can bang on a pipe, or is stranded somewhere, but has a flashlight). But that's "progress" for you... It's sort of like when all the libraries went to digital "card catalogs" and IMMEDIATELY did away with their paper card catalogs. While I don't think they should have continued updating and adding new ones, holding on to at least what they had -- even if they were stuck in storage somewhere -- would certainly protect at least a large portion of their record keeping in the event of a massive server failure, or something.
When considering something as sweeping and with as widespread consequences as usurping a huge chunk of available broadcasting bandwidth, EVERYTHING needs to be considered, NOT just how much faster it'll make downloading books or movies on your iPad!
