what about simple spyware, infected browser with corrupted homepages, those sad slaves will give it everything they got...
That's my concern. If websites start embedding the miner then I imagine popup blockers or even the browsers themselves will take steps to prevent the function of this coin. If the wallet/transaction system is separate that wouldn't be the worst thing. But if they aren't it'd remove the main purpose of the coin.
