Logitech Harmony Remote
a software to configure the Logitech Harmony remote control (model 555 in my case and the best RC I've ever had). The software is written in java and the download is quite huge (about 55MB). It looks exactly the same like in windows and for some reason, one has to reboot after the installation (maybe so it does not just look like in windows but feels so too).
Freeware (well, makes only sense if you already bought the remote anyway)
