Hi, so as far as I can research there are a couple different ways of getting a wii to send data to PD in Linux. Most involve external apps sending data to PD in various formats (yuck). The easiest would be this: http://youngmusic.org/wiki/index.php/Wiilib if its makefile actually made all of the required code (but it doesn't). Can anyone familiar with writing externals take a look at this (I'm pretty sure the code is all fine, it just needs makefiles built).

Edit: Well Mike Wozniewski just updated his wiimote external to work with libcwiid 0.6.00 (the current version in the ubuntu hardy repos), so all is looking up (and down, and roll, and pitch, and X, and ....).
