Another Horcrux theory

A friend suggested to me that Dumbledore was a Horcrux, but she
thought that he realized it himself before the school year started.  I
have a slightly different idea - what if Dumbledore became a Horcrux
in the course of Book 6?  Where and when?  In the cave, with Harry. 
What if the Horcrux wasn't the locket at the bottom of the chalice,
but the potion itself?  If the only way of removing the potion to
reach the locket was to drink it, then the drinker would end up taking
into himself Voldemort's soul-fragment.  He'd become the Horcrux.  And
Voldemort would think this is a foolproof plan - the only way of
destroying the soul-fragment would be for the carrier to die, and who
would agree to his own death?  Voldemort can't imagine it, so he'd
think his soul would be safe.  

This explains 2 more things: the anguished memory that Dumbledore
"channels" while drinking the potion - that's Voldemort's (or
Riddle's) memory.  Maybe his soul can still experience the atrocity
committed on it when Riddle gave himself up to evil.  Perhaps this was
his first 'dark magic' experience in the cave - whatever he did to the
two children there.

And Snape's reaction when he AK'd Dumbledore on top of the tower.  His
hatred and loathing - it wasn't for Dumbledore, it was for Voldemort,
whom he was also killing at that moment.

This leaves me with the puzzle of the locket.  I think it was fake all
the time.  Voldemort was a collector of trophies.  If the locket
didn't contain his soul, he wouldn't waste it as mere bait.  He put
the false locket in the chalice, and the real one is somewhere else -
probably not a Horcrux at all.  And the note?  Perhaps Dumbledore put
that message to Voldemort in there himself - a warning that he'd
figured out his plan and destroyed it.  I don't know what R.A.B.
stands for, though - maybe Godric Gryffindor had a motto that would
fit.  Or maybe it just means "Riddles Are Bums".  I don't know; I'll
have to think about it some more.  Anyway, it's just another theory to
consider.
