to do something practical, someone like minerGate has to find a way to send hashing task to the ps4 cpu and gpu via the browser, or basicly the ps4 browser is not allowing those task to pass though to the system.

the other idea is developing a native app for mining and publishing it via ps4 store, but hey sony will never allow that i believe.

perhaps only when they make SonyCoins, as at the end i think all of the company will switch to those currencies, and it has a dual property of stock and money.
