Thanks for the bump. I have some catching up to do. :)

A long time ago, I read an SF novel (might have been shorter than a novel) involving teleportation (there are thousands of such stories), but this one had the interesting feature that the person being teleported actually dies at the sending end, while the person who emerges at the other end is a duplicate with the same memories. So the emerging person is undisturbed by the death of his predecessor, because from his point of view he's the same person. But the poor devil going into the machine knows he's going to die. His only motivation is that he knows he's sending his duplicate off somewhere where he needs to go. The idea was well-developed. I don't remember the author, or even the plot, only that neat feature of the teleportation system.
