This is awesome but I don't understand the link to cryptocurrencies. Why do you think that cognitive radio and WSD's will boost the use of Crypto-currencies?
Because the success of crypto currencies is directly linked to the accessibility of the internet. When these devices are standard clean water will be more luxurous than internet. It will also lower the skills you need to use bitcoins, now it's still for the people who have enough brains and balls to adopt it. You need a computer or online phone to use it.
It's also a good technology for hardware wallets. You pay once for your wallet and it's always online and has enough bandwidth to download the entire blockchain.
We are always hoping that big companies will start using bitcoin but i think new technologies that make internet more accessible will have a bigger impact. I will definitely keep my eyes on the developments. It will change this map completely:

10 years from now you will have a cheap WSD hardware wallet that's always online. You use it to pay person-to-person, in the supermarket, in remote places, really everywhere.
I really see potential in this, the company that makes a good WSD hardware wallet will be rubbing it's hands out of joy. It will take bitcoin everywhere.
The reason google/apple/samsung are creating this technology is because the providers are stealing away potential profit from them. They don't make any money on SIM-cards and it limits the accessibility of the internet, thus their store-sales, they need free open internet to maximize their profits on their stores like iTunes etc. Bitcoin will also profit from this. We should thank them for taking the fight to the telecom providers.
