Gus you are knocking it out of the park. The Universal Standard is a great idea and I can see how it will lower our costs to market.
For smaller boards for the IOT market, please consider RFM69 and RFM95 LoRa. These low power, long range radios are way better than Wifi when it comes to battery powered units.
I know IOT is not your target market, but it will be a non trivial segment of your bottom line if you embrace it.
