Skype for Teaching -- whiteboard, etc...
Give an additional module to the basic Skype , and call it 'skype for teaching' with whiteboard function and other functions that may be useful for people using Skype for teaching , but NOT using the business version as that is not specific enough in scope / purpose to be used for Teaching / Tuition over skype.
I have just been looking for a whiteboard option on skype. What a coincidence. Good one Paul.
