Well not really sometimes.. I have an Onkyo NR-818 AMP and I can use the Onkyo Remote to control the PS3. If your PS3 (Slim Model Only) and your Pioneer AMP does CEC the AMP remote may be able to control it.
Very cool, thanks for mentioning that.
I personally still see the harmony approach as giving you complete and flexible control over the systems, but it's nice to know bits like this for users who aren't going down the harmony route.
