How to remote control OpenOffice.org Impress

Dear lazy web,

I want to control OpenOffice.org Impress through my remote control on Linux. Does OpenOffice.org Impress has a lirc plugin or is there another easy way to do it? The system that hosts the presentation is used for other things, too. Therefore the current active windows is not always Impress. Sending a key code to the active window won’t work.

Update: The computer has two screens: A TFT and a video projector. It is used for audio recording and hosting the presentation. The active window on the TFT is the audio recording application. The presenter can only see the video projector and should be able to control the presentation with a remote control that works with lirc.
