Books like Ribofunk

Has anybody found any books like Ribofunk by Paul Di Fillipo? I remember being absolutely floored by how awesome this book was when I read it a few years ago, and everyone I've lent it to since has had the same reaction.

Has anyone found books that deal with similar themes of genetic modification and biohacking in a dystopian future?

While we're at it, anybody know of any books similar to the Takeshi Kovacs trilogy by Richard Morgan? I was extremely saddened when I read that he had decided to stop writing with this character.
