I work for a company who is developing integration between various 3rd party systems in the field of engineering systems. I am incredibly interested in the idea of putting sensor and other kinds of temporal data on the block-chain. It would be a great way to avoid needing to invest in the otherwise necessary infrastructure to support such use cases. So basically the same thing as what is being done here for weather, except things like pressure, flow, temperature etc readings for real world equipment. Probably wouldn't even have to be obfuscated in any way as the intended end user could put into the data unique IDs that only they know how to correlate to the real world equipment.

Figures. Thanks for the info.
