Here's what I use, it's an IR/RF remote:


You can also buy the remotes and receiver separately. I've had good luck 
buying used remotes on eBay.

I have one receiver in the basement, blasting IR to a USB-UIRT2, 
connected to the BE server. When tuning, the USB-UIRT2 also blasts IR 
out to the satellite receivers in the same rack.

My frontends connect to the BE using LIRC's TCP mode, so I don't need 
any IR receivers at the frontends. All of my frontend remotes are 
programmed nearly identically (using the "clone" feature), where each 
room is a separate "device". If a remote gets lost, you can just grab 
another remote, press a device name button to say which room you're in, 
and start using Myth.

You could add a second RF receiver to blast IR signals to your audio 
receiver, if it's not line-of-sight from your server. These remotes are 
highly programmable, so you can learn any signal for (almost) any button 
press, and do multi-step macros.
