I'm guessing/hoping there's a sticky in the works or some word from c74 and I'm sure there will be an update to come.
I'm very excited to see if anyone will develop an external for communicating (well) with the dictation speech option. This has so much creative potential.
neither aka or ajh versions of the wiimote external work on ML, some changes seem to have been made to relevant .framework files that are called by wiimote. I'm still not sure if it was just names that were changed or something more, need to find someone os x savvy. until I know what changed I'm not sure how complicated updating wiimote would be.
