Voldemort is pretty stupid. During GoF he performed a ritual in 
which he passed Lily's protection into himself. Maybe he took in a 
piece of  her soul.

to which I reply and add a few...

Interesting ideas but these get me confused:
Did I miss the part of the conversation where humans can be 
horcruxes?  I thought at first that Harry became an unwitting 
horcrucx when Lord Thingy tried to kill him and it backfired.  But 
then again, did it backfire? For if your theory is correct and 
humans can be horcruxes for another, wouldn't the killing of Lily 
create the Horcrux!Harry?  Or was Lily meant to be the Horcrux from 
James's death... "Stand aside you silly girl" (bad recollection of 
V's statement in Harry's memory).
If Harry is the Horcrux then that would support those who believe 
the series will/ must end with the deaths of both V and our Harry. 
If Harry has to destroy all the horcruxes and Voldemort, then he has 
to die in the battle.  Is this little bit of V the part that 
intrigued the sorting hat, that led Harry to the sister wand, that 
makes him a parselmouth, that will doom him to sacrifice in Book 7?

Another pet Horcrux theory:  The Half- Blood Prince's Advanced Spell 
book is a horcrux.  Why does Snape leave this important book behind 
in the potions classroom closet?  Wouldn't he want to keep such a 
personal collection of nastiness and hard work/ clever spells?  Why 
is it left to be handed out or taken?  If it is a Horcrux, does 
Snape know? Is that why he wants it back (ESE!Snape)? Or, does he 
somehow want Harry to end up with it for various, as yet unknown 
reasons (ESG!Snape)?
Interested in all your thoughts,
