No, I haven't seen a component yet (that I've used) that has IR out jacks on the back that act like an IR repeater system. In fact, hard wire IR ports actually require the IR signal to have the carrier frequency stripped off of it (typically) so that it will even work.
Only a few products even are controllable via the IR inputs on the back.
Quite often the IR output on the back is used when a VCR needs to change the channel of a cable box. Or when a Tivo needs to control your DSS channel. Some brands do control their own products directly, but it is highly proprietary from what I've seen. Something like a Mitsubishi TV w/Mits. VCR or something similar.
As said, an IR repeater system is the way to go, and if you are irritated by IR bugs sitting on the front of your components, you can take a few hours and open the components up and bury the IR emitter inside the pieces of equipment. I did that for all mine so that while most pieces are IR controlled, you can't tell, and there are no wires hanging off or bugs that small hands will remove from the correct location.
