Yes, it is all about IoT.

About Ethereum; Have you gotten a good insight in this? I know what a
blockchain is, but assuming a million sensor generating 12 values per hour,
we are talking GBs per hour of data added... And 1 million is hopefully on
the low end.

I would love to hear more about it...

Cheers
Niclas
