RaeMote is a N900 desktop widget that turns your N900 into an Apple Remote that can control your Mac Mini, MacBooks and iPod docks via IR. RaeMote has been developed by Thomas Perl and is available for download in the extras testing repository. The widget works as expected and has surprisingly good range.
I was able to control my Macbook from around 5-6 meters away without having to align the device and this worked from wide angles as well. Here is a video of the application in action. If you haven’t enabled extras-testing, here’s how to do it.
