Topic: ChumbOS Launcher
I have just uploaded to sourceforge the ChumbOS Launcher application.
If you would like to give it a go, you can find it here: http://sourceforge.net/projects/chumboslauncher/
It cannot change the volume on the chumby since I don't know and easy way to do it programatically in C.
I saw the source code for amixer which is a bit hairy...
If you know of a way to change the volume on the Chumby in fast manner (not by using chumby_set_volume or amixer in system(...) call or such) I would be grateful and will include it in this launcher.
