How about this:
Take a working (conscious) brain. Replace each connection between neuron X and neuron Y with a pair of humans sending e-mail or talking on a phone or whatever. The neurons are still alive. They produce signals, which are read by a human (via some piece of equipment), sent to a receiving human, who then stimulates the appropriate input of the receiving neuron.
The brain is still functioning (albeit with a time lag). The neurons are doing the information processing, they are communicating the same information to each other that they otherwise would. But they could be seperated, kept alive in little dishes, as in the previous scenarios.
I agree that the brain as a whole organ/organism is not alive, although its components are. But in exactly what way would this not qualify as conscious, if the original brain does qualify?
