The Empeg has two types of Infrared reception. One is used to accept command from remotes. Any remote that operates in the 38-40Khz range should be seen by the Empeg. And therefore with Hijack should be able to be used. The Empeg also has a IRda port. At this time this is not used(by most). The IRda port will allow two way communication. So any device that uses this port will have to have additonal software installed to send the commands on to the player app.

Now I am not the expert on this, but that is the way I think it all works. Someone chime in if that is not all correct.
