For this idea, you have to assume that either A) it has already been done, so that you really will not be changing anything, or B) you can somehow copy a person's consciousness without interacting with the matter making them up at all, so as not to introduce any disturbance. The first seems too convenient, and the second unlikely, IIU quantum mechanics correctly (and I may not...).

If you are interested in a fictional account of exactly this, read Spider Robinson's _Deathkiller_. A sequel, _Lifehouse_ was written, but is much poorer, IMHO.

Wolfkin. (in a week or so)
