The benefit to the RF units when your equipment lives in a separate room (closet) is that you don't have to buy a complete IR distribution system or find a place to install the IR receiver - the RF base station includes a very high-power emitter that can often cover the whole rack as well as six outputs for individual IR emitters that can be stuck in place over individual components' IR windows. Harmony doesn't currently offer an RF solution, which puts you in the position of needing an IR distribution system. Since NickScull's equipment rack is in a closet, the discussion turned to the RF remotes. If your equipment rack is readily at hand, the RF capability isn't as necessary.
