I just finished re-reading the first two books. It is a habit of mine to go back and re-read the series after I finish the latest offering. This time it makes even more sense.

In the first book Dumbledore talks about how he wouldn't remove Harry's scar even if he could be scars can be useful. In Chamber of Secrets he talks specifically about the abilities that Harry recevied based on that scar and how some of Voldemort was transfered to Harry. I know that by the fourth book Harry is activly having issues with his scar and sees the murder of the groundskeeper. He begins to tell people about how the scar is acting up. It is around then that Dumbledore stops talking to Harry about the scar.

We had more then enough info to figure out that Harry is a horcruxes but most of us (myself included) managed to miss it. I loved how Harry thinks of Hagrid as a giant when first meeting him and then the word giant is dropped. I am finding that JKR told us more then we thought and that the clues are just being teased out now. Heck, they were not even clues but we managed to miss them. Good stuff.

I do think that Harry was a horcruxes. Dumbledore tells Harry that Voldemort probably meant to use Harry's death to creat his final Horcruxes. It sounds like the spell to make a horcruxes has to be completed at the time of death since the horcruxes has to be created when the creator takes another life. JKR never explains the actual process but I get the real feeling that the prep work has to be completed before hand and then the spell is ocmpleted with the actual murder. Pure suposition on my part.
