Horcruxes, The Hat & The Map

I've been looking for references in other posts, but so far have 
found none that remark on the possibility of the Sorting Hat and 
Marauder's Map being Horcruxes or a kind of magic related to them. If 
there are, please point me.

>From the Mugglenet Interview:

ES: Has the Sorting Hat ever been wrong?
JKR: No.
ES: Really? 
JKR: Mm-mm. Do you have a theory?
ES: I have heard a lot of theories.
JKR: [laugh] I bet you have. No. [laugh] Sorry.
MA: That's interesting, because that would suggest that the voice 
comes more from a person's own head than the Hat itself -
JKR: [makes mysterious noise]
MA: And that maybe when it talks on its own it comes from -
JKR: The Founders themselves.

Me again:  They both have something of the personalities of their 
creators. They seem to be used in a similar way Nagini is. 

It obviously didn't take a murder to create the Map and Hat...so how 
were they made? The murder must make a qualitative difference in the 
magic to prolong the maker's life, since the Sorting Hat and 
Marauder's Map didn't prevent those who made them from dying. Is it  
possible to put part of yourself in an object other than your soul? 
Ideas?
