	The red shift must be asymptoptic, because radiation cant be
shifted to negative frequencies... 
	It seems like the situation here is the same as if you have 3
observers: one in the middle, and two receding from him at 0.9c in
opposite directions.  The guy in the middle sees two objects at 0.9c;
but what do the other two see? I think time-dilation is the clue
here(?)...
