There are many remote apps to let Android devices control XBMC installations. Is there anything that would act as a generic keyboard or mouse, to allow an Android phone to control Raspbian, ChameleonPI, or any other distribution?
Raspberry Pi Remote Control uses SSH to controll the RPi. Configuration seems to be limited and you cannot change the audio output. I need to use a USB DAC so this probably won't be useful. https://play.google.com/store/apps/details?id=com.raspberry.remote&hl=en
NetIO looks good, I'm trying it out now. http://store.raspberrypi.com/projects/netio
Both of them seem to be targetted at media applications.
