What for, exactly?

No, I don't.

Perhaps we should clarify something here. Are we intending to auto-create a new 
input device for every IR command set we see arrive at the IR receiver? I've 
been assuming we're not going to willy-nilly just auto-create a new device for 
every IR signal we happen to catch passing by. The receiver should only be 
passing along input events for the codeset/remote I've told it to listen for 
(which by default, is the codes for the receiver's bundled remote). Otherwise, 
yeah, I'm going to wind up with my htpc powering off when I hit the button on 
my harmony remote that is supposed to turn off my tv and amp.
