Mapping Buttons in Android

The LIRC library allows you to use a remote control to control software on a Linux computer.  Because of the wide variety of supported remote controls, LIRC uses a mapping system to allow the user to decide which buttons perform which actions.  Programs that support LIRC have a list of "actions".  For example, Mplayer has an action called "pause".  On my Streamzap remote, I map the Play and Pause buttons to the "pause" action.  This allows me to quickly pause and unpause the video.

Android apps need to implement this feature.  Right now, if I want to pause MX Player, I have to click the Mele Fly Mouse button to bring up the player controls, move the mouse cursor to the pause button (before the controls disappear again), then click the pause control.  If someone is calling (the main reason why I would pause a video), it could take a few seconds, so I could miss the phone call.  My wife just started muting the TV instead of pausing it.  If MX Player supported mapping buttons, I could use one of the buttons on the face of the Mele Fly Mouse to pause and unpause the video.

In general, I would like to do this in all of the apps.  Netflix, Crackle and Hulu (really any video playing app) should implement this feature as well.  This feature is one of those things that prevents the tool from being adopted by the mainstream as a potential Cable replacement.
