<p>I'd like to  use the Wiimote (accelerometers, gyroscopes, infrared camera, etc, etc, etc) on various applications.</p>

<p>It's a bluetooth device, and I know others have connected it to their computer.</p>

<ul>
<li>What's the easiest way to start using it in my software - are there libraries for C#, for instance?</li>
<li>I want my software to be usable and easily installable - what's the current easiest way to connect a wiimote to the computer?  Can I make that process part of my software installation?</li>
</ul>

Coding4Fun had a managed C# library up that would allow you to interface with it but it seems their site is down right now.  Though I think they used the Robotics Studio so that may be a place to start.
Found it...

Oh and I forgot to post a link to these videos I saw quite some time ago.
