It would be cool if Google accepted Bitcoin so you could get paid in BTC instead of through the annoyances that typically occur with paypal (im talking adSense). Since I don't see this happening anytime soon, someone could do something similar, but please don't be as anal as Adsense with their censorship. I've gotten a lot of blogs banned for nothing until I eventually gave up.
i would not be surprised if this were to happen in the future.
There is still a-ads that will pay you in bit coins but they pay per impression not per click
