Adam has a very good idea using an RF remote control so you don't have to have a key pad and only have to run speaker wires to the in-ceilings and you could use the surround back outputs to power those speakers.
You do not have an IR in on your Onkyo. The RI is proprietary (sp.
) and works with their iPod dock and other Onkyo products.
Keypads in manycases are just remote controls that transmit IR over a cat5 wire to the MSU and the MSU distributes the IR signals to each component via IR flashers.
So you could put a keypad in the wall and run cat5 wire to the MSU and add flashers to the front of each component. (you will need to have an anlog connection for each component to be used via Zone 2 of your reciever)
Now if you go RF then it is essentially the same except you will use the remote to send the IR data via RF to its MSU which will then use flashers to control each component.
My current whole house system I have a multizone Integra that I program via a laptop and then I have a minilcd monitor so I can view my music lists.
