Have you read Vinge's A Fire Upon the Deep? You might enjoy it, if Excession sparked your fancy.
Note: Vinge is more circumspect and less obvious about what's going on, so expects you to infer more than Banks does. Also, would recommend reading Fire without Googling it, as that would spoil one of the nice literary sleights of hand.
