BlazerRazor has posted some details and a screenshot of whats coming in the next release of his app for DS:
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.
Next upcoming release (0.2):
Updating and calibrate keyboard.
Moving left and right mouse clicks to left and right key, and y and a - better comfort.
Be able to enter TCP and UDP on client-side (only server-side has this option now).
New media control extended (MEX); with extra features, great for media center and similar.
If you have something you would like added, make a wish in this thread
