Hunt is right, on the web they do say that peer groups are not compatible with route reflectors due to route withdrawal problems, I don't know about the book. Here is a link to the website that states it about 3/4 of the way down the page, I also have no problem running redundant reflectors using peer groups, and the client routers are not running IBGP with each other, according to this link that is a requirement.
