I really love the idea! I even can use in my own websites. However, It reminds me the tv show Silicon Valley, which the last chapter of last seasons they used their compress technology on every smart machine. That reduce all prices. Well, it looks like the same idea but this one more then a TV Show it is real!
I want to learn does oyster use too much effort on web nodes. For a website owner, all we have to do is add the script. But on the other hand, who comes to our website will mine for us. If they realized they are mining for us with too much effort for their machines, they won't come to us again. So can someday tell me about this?

But as I said before, the idea was brilliant.
