I have my (dedicated) HTPC in my lounge connected directly to my TV for maximum performance. I have an Xbox in the bedroom with a Harmony 525 as an extender only (it has never seen a game, and I haven't even unwrapped the controller for it).
I want an option to control my HTPC music mainly from my iPad (yes Rusty, to justify the purchase :p ). Plus the same solution should work from my desktop PC upstairs too. Here's hoping!
