I'm not sure I understand. It seems like you're implying that the two people would be moving away from each other faster than the speed of light, but I was under the impression that that's not the case. I thought that each person would observe the other travelling at C?

I think they would observe each other traveling at C but would experience visible time dilation (in the other person's frame of reference).
