Limelight is a presentation management application, that currently supports text song lyrics, images, powerpoint (2007 is not yet supported in Apache POI) and pdfs, but will support eventually support video and other formats as well. It also supports the apple remote on OS X. It is still beta software and there maybe some bugs, so use at your own risk. Any questions see the FAQ. It can also export slides and powerpoint to images.
