Ginger:

<<I think the light bulb has gone on.  So what you're saying then is 
that as long as there is one Horcrux outside the body, that LV can 
regenerate (for lack of a better word) as many times as he needs?>>

Yes, that's exactly what I was trying to say! :)  I'm glad it was 
clear - I feel the same way about Horcruxes as I felt when I was 
trying to wrap my brain around how time turners work ...

Ginger:

<<So LV's reason for having 7 (total) isn't that he can revive 6 
times, but that he is protected even if something happens to 5 of 
them and someone tries to kill him.>>

Yes, exactly! And we've already seen that he had good reason to 
create more than one, as the ring, diary and possibly the locket 
have already been destroyed.
