If I may go into fanboy mode for a moment, I'd like to say that in my opinion the Library itself is one of the crown jewels of the federal government. It is also definitely worth a visit if you're ever in DC. They give free tours of the Jefferson building, and besides the beautiful architecture of the building itself, there are some very interesting exhibits on display. There's a surprising amount to see, and the staff are great- very knowledgable and friendly.
Besides its main missions of supporting congressional research and acting as the central repository library, the LoC also does a ton of great research on media preservation and archival practices... I got to tour one of their labs once- in one room I talked with an expert in the chemistry of inks used in the 18th and 19th centuries, and in the next room heard from other people who specialized in CD and audiotape manufacturing, who could talk about how specific manufacturing plants in Japan changed processes from year to year and how that affected the archival lifetime of their products. Just amazing stuff, and that wasn't even scratching the surface.
Doesn't mean it's not a good idea, but being naive about it won't get you anywhere useful.
Were these standard encumbrances that hardware and software makers put to try and lockdown their products, or was there something special about farming?
The very high cost of the equipment if it were bricked for license violation, and the very narrow windows for being able to use the equipment (if you need to call John Deere and have them re-enable your tractor you've just potentially lost out on an entire seasons revenue) were also big factors. Many of the farmers that we talked to were fed up enough that they would have risked it, but between our own direct legal risks, and the risk to our reputation if our customers equipment started getting bricked, was enough to stop us from moving forward.
You run your own software on your own computer with your own sensors.
The other issue is that I'm not sure we would have gotten as many buy-ins from the farmers. Many of them were very frustrated by the lack of interoperability between different pieces of equipment, their sensor data being locked behind DRM schemes, etc. They wanted to integrate the hardware and software that they owned, and wanted something that would let them do it piecemeal and with relatively little risk to their hardware. A complete overhaul wouldn't have helped with integrating their historic data, and would have definitely had a higher upfront cost and risk associated with bricking their equipment.
I think in general companies go more and more aggressive and ruthless to remain profitable and fight opposition, that's our economy..
