This is a huge accomplishment and you can bet that soon enough the hackers will be streaming all kinds crappy 4 bit sounds to their wii-motes. Let the fun begin!!!
Once again Carl, great work!

Next up is integrating the Speaker functionality into the other Windows Wii-Mote apps, as well as the Linux and OSX wii-mote programs. Developers will want to check out the WiiLi wiki for information on how to initialize the wii-mote speaker and send sounds to it.
