That is just too cool!!
Too bad he just skips over the part where he tells about how he made the interface.
Is this what you`re looking for?
and $4 is a steal because of the crappy AUD right now.
That looks like fun to toy with. I'm still waiting for my arduino nano to arrive to get me introduced to the world of arduino. (sorry Frits! I may just go over to the dark side) So I this really gets me thinking about experimenting with the wii remote.

Wouldn't you just need a bluetooth module that hooks up to a micro?
All you'd have to do is find out what security code the wiimote uses to connect, and then program that into the bluetooth. Most modules have their security and connecting programming all within the module.
Imho, I don't think you get the Bluetooth & HID stuff running on a micro like AVRmega or PIC. For these you need a little bit more power. A gumstix board (ARM processor with Linux) for example can do this job.
