I'm reading the first one in your series. Only 10% in, but liking it so far!
(edit) Your book is eating my weekend. I need to do work! :-P
Your AI seems to be a utilitarian, with a rather simple, if interesting objective function. That could lead strange places. (I'm at 26% of book 1). (Actually, now that I think about it, that objective function isn't all that simple.)
(edit^2) Holy crap! Weekend: gone. This is one of the better sci-fi books I've read all year though. (~56%)
