Could you be more specific about what/where you changed to get the Ink Preference Pane? I know if you go to /System/Library/Components/Ink.component/Contents/SharedSupport/ and then load InkServer it shows up, but I’m not sure if it remains after restart?
Unfortunately, I’m not sure about the ultimate possibility of this working, because of the “pressure” bug that was mentioned above in this thread. According to this article: http://docs.info.apple.com/article.html?artnum=107262 it seems that Inkwell relies pretty heavily on the pressure setting from the Wacom software driver. But if changing settings in the Wacom software can change the pressure reading the system sees, shouldn’t Wiimote Whiteboard be able to do the same thing?
