Remote Touch DS gives you the opportunity to remote-control your computers mouse, keyboard and other things from your Nintendo DS hand-held console. This solution is not like remote desktop, but more like an advanced remote control.

The solution is client-server based, obviously, and requires you to have a server running. It is not plugged with synergy, it is my own solution. The server receives commands from the Nintendo DS and acts according to them.

Current release (out now; 0.2):
Media Control Extended (MEX) - good for Media Center or similar.
Keyboard fully calibrated and working with key press sound for comfort.
Remote restart or shutdown of your computer - good for those late night movie sessions where you just want to shutdown your computer directly from the comfort of your bed.
Added support for a "rtds_settings.txt" config-file on your cartridge with connection data - look in README.txt for more info.

There will be *unix and OSX versions of the server-side.

Source will be released at a later point, need to clean up the codebase and stuff.
