Human clones? We're still finding the little quirks with animal clones, like accelerated onset of age related diseases. If human cloning is to be viable, cloning must be at a scientific level far more advanced than what is currently published. Then again, it's likely some of the more fringe scientists working on it may not be publishing for obvious reasons.
I think it's possible, but we are not likely to see human clones any sooner than 10 years out.
