I've been researching these pretty thoroughly but I can't give you a definitive answer until mine arrives tomorrow.
However, from what I understand of this technology and specifically from what I've read about the Harmony RF-to-IR blaster box, it just needs to be in the same cabinet with your devices. Line of sight is not necessary due to the fact that the IR beams it blasts can bounce off the cabinet walls and will probably be picked up by your devices.
The kit also comes with a tiny little IR emitter that you can affix to the front of a device if it is not responsive to the blaster. This emitter is hardwired (via standard 2.5mm audio cable) to the blaster box. Just affix or place the emitter eye in front of your device's IR window. This ensures pinpoint accuracy of the IR signal to that device.
Your other devices will need to be able to pick up the IR blaster's beams, either directly or by bouncing off the cabinet walls. Most have not indicated that this is a problem.
One important potential issue you need to consider
Since the remote is RF only, it cannot control your TV without the assistance of the blaster box (or its IR emitter). So, you will either need to route the emitter cable out of your cabinet and onto the front of the TV where its IR window is, or you will need to insure that the blaster is positioned in a location that its beam can reach the TV.
The same goes for the iPad/iPhone/iPod control interface. To use the smart phone interface to control your TV, you will need to have the TV within range (line of sight) of either the IR blaster hub or its tethered emitter eye.
Hope that helps!
