well I should put my hints and tips:
usb battery pack for wiimote: takes over the need for using or changing batteries
Retort stand+bosshead+clamp: give better stablity to remote.
Software: allegedly most interactive whiteboard software works with it, there are a few freeware viersions out, most seem to be very primary.
Problems: havent worked out right click yet, Could not find a 100mA IR LED so used a 50mA. will find out if my guinea pig is having any problems.
