The more I look around the internet the more I think this project is going to be do-able because there are so many people who have already done things like this, even projects way more advanced than what we're tackling. Below are links I've found...apparently it's much easier to get a wii to talk to a windows machine because of the Bluetooth protocols. I'm gonna see if I can get my hands on a copy of Vista or XP and load it onto my Intel machine. There's also a patch written in MaxMSP that will allow your wiimote to talk to your machine.
