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.

Release notes:

* Minor changes on the server backend – possible problem with shutdown/restart on XP (maybe) fixed.
