Since I have started my new postion at the DMZ my main focus has been hacking the Wii Remote to use in an external application. I have explored a great deal of different software and I have found a combination that seems to be working very well.
A piece of software called OSCulator that does a great job in connecting to the Wii remote and letting you manage what you want to do with these signals. Some of the basic options include mapping the X and Y co-ordinates to the X and Y values of the mouse, letting the user use his Wii Remote with his mouse and so on. On of the more advanced features includes converting the Wii Remote values to a communication protocol called OSC (Open Sound Control).
With this new signal I found another very important program called Oscar which converts this signal from OSC to standard XML which almost every external language would understand. A simple XML parse can be written in any language to parse the XML data into the appropriate variables.
Using the common 3D Flash library called Papervision I have managed to create some examples.
If you would like to try anything out just add my SVN repository : http://vladcazan.svn.beanstalkapp.com/wiixmlparse/
Here is a basic Wii Remote XML Parse to use in flash with OSCulator and OScar:
