That ignores data compression Markus. DNA can carry the full coding of a human organism in about 10^8 bits, so that could be the minimum required if there was some way to assemble the organism without needing a lifetime of growth and experiences. Thus, the lower bound would be transmission of the basic code of a human in about 5 microseconds. Add in the wiring diagram of the brain and neural weights encoding experiences etc and it would clearly take longer. So that's narrowed the problem down a lot - we can say with reasonable confidence that it may actually be possible to transmit the full information content of a human in a time period somewhere between 5 microseconds and half a million years.
