mistborn does this. Mistborn, especially (the book, I mean)--has House Tekiel, named after the username of one of the girls on Timewasters', and a Lady Stace White or something like that is buried in the middle. Entropy, another guy on the boards, shows up as a dead body. I think he started a thread requesting name ideas, but I can't remember. He'd be able to give you more details, of course, but I did think it was a fun idea, especially with the need for so many names as he had in Mistborn.
